A 15-year-old’s left-hand amputation has changed policing at French school protests. New footage adds evidence, but does not establish pickup, identify the munition or settle responsibility.
Now established
- The pupil’s left hand was amputated, he remained hospitalised on 7 October, and the lycée-movement grenade restriction has been confirmed.
A 15-year-old pupil in Lens has lost his left hand. Surgeons amputated it after a grenade explosion outside his school on 5 October; his right hand needed a graft, and he also suffered wounds to his face and chest. On 7 October, he remained in hospital. Whatever investigators eventually establish about the explosion, the permanent injury is already a fact. 170 154
His mother rejected the explanation that he picked up the grenade and announced that she would file a complaint within hours. Speaking to BFMTV on 7 October, she said, in translation: “They stole his life.” Her account is not an investigative finding. But neither is the pickup explanation, which has travelled much further than the evidence supports. 154
France has now suspended a stun-grenade capability at high-school protests while the circumstances are clarified. The restriction has no fixed end date, but it is not a general ban on police grenades. The precise munition responsible, the boy’s hand movement before the explosion and the legality of the particular police shot remain unresolved. 123 135 108
On 1 October, HeyDay News reported spreading school blockades, fires and investigations into possible police violence. The Lens injury happened afterward, on Monday 5 October. A police instruction followed on 6 October, and Interior Minister Laurent Nuñez publicly explained the suspension on 7 October. This is a new permanent injury and a concrete change in policing—not another update to the earlier national arrest tally.
What happened outside the school
Prefect François-Xavier Lauch placed the injury at about 10:30 local time outside Lycée professionnel Auguste-Béhal in Lens, in Pas-de-Calais. Approximately 200–250 pupils had gathered. His account described stones, fireworks and mortars thrown at local police, followed by deployment of a company of CRS riot police. That establishes the authorities’ account of the confrontation, not that every pupil threw anything or that the injured boy did. 115 107
The boy lives in nearby Wingles and was taken to Lille for treatment. On the evening of 6 October, Wingles mayor Sébastien Messent described his surgery, left-hand amputation, right-hand graft and other wounds, saying he was sedated and sleeping extensively. Lauch’s initial statement that his life was not in danger should not be mistaken for a reassuring prognosis about his disability or remaining injuries. No public medical record, discharge date or detailed rehabilitation assessment has been established. 170 107
Some reporting got the injury wrong. FRANCE 24 English’s 6 October programme described both hands being lost after pickup; the BBC’s initial 5 October report described one hand and competing explanations. The subsequent surgery account establishes one left-hand amputation, not two. CNN on 6 October described lost use of a hand after an attempted pickup, while NBC News that day explicitly left open whether the grenade struck him or exploded after pickup. Loss of use understates the confirmed amputation; pickup remains unproved. 14 1 170 10 22
The disagreement began with early police-union accounts. AFP, citing a union source, reported that the boy appeared to pick up a sting-ball grenade fired by riot police. A girl who said she was near him told La Voix du Nord that he neither picked it up nor caught it. On 5 October, Béthune prosecutor Étienne Thieffry expressly left open whether he recovered a grenade that exploded in his hand or whether it landed on him. 1 119
By the evening of 6 October, Thieffry supplied a provisional police sequence: warnings to disperse, projectiles directed at CRS officers, burning bins, tear-gas grenades and then at least one stun grenade. That reconstruction does not identify which device caused the injury or determine its trajectory. Nor does it settle whether that particular use of force was authorised and proportionate. 171 170
A video with a missing moment
Amateur footage authenticated by franceinfo and published on 7 October at 17:16 adds evidence, but not a verdict. A grenade lands on the ground at two teenagers’ feet in a car park, with a CRS line behind them. A third teenager, among a group of about fifteen apparently moving away, bends forward with a hand extended toward it. 108
He then leaves the frame for a few seconds. A detonation is heard, and he is subsequently seen running away with the others. The visible frames do not show him taking hold of the grenade. The sequence challenges the explanation that it landed directly on his hand, but the missing view prevents it from proving what his hand did before the explosion. Bending toward a grenade and visibly picking it up are different observations. 108
Franceinfo said on 7 October that IGPN investigators did not yet possess the footage. Culture Infos described investigators as examining it. Formal receipt therefore cannot be treated as settled; franceinfo’s directly described position at publication was that the images had not reached investigators. The boy was expected to be interviewed very soon, without an announced date. 108 111
IGPN—the Inspection générale de la Police nationale, France’s national police watchdog—is investigating suspected violence causing permanent disability or mutilation. As of 7 October, the CRS officer holding the launcher at the relevant moment had been heard as a witness. He had general authorisation to use it; investigators still needed to establish whether he alone launched a stun grenade and whether the particular shot was authorised, proportionate and legitimate. 108 110
The BBC’s 6 October account implied that an officer had already been charged specifically over Lens. The subsequently established Lens status is a witness interview, not a charge. Reporting of an officer placed under formal investigation concerned a different pupil’s injury in Saint-Ouen-l’Aumône. Neither opening the Lens inquiry nor suspending a weapon proves an offence. 18 108 146
A real restriction, not a blanket ban
Actu17 reported that a 6 October instruction from national police director-general Louis Laugier suspended “la grenade ASSD (marque Alsetex) projetée par lanceur”—an Alsetex ASSD grenade projected by launcher—only within the lycée protest movement, until the Lens circumstances were established. The wording is multiply reported, but no public facsimile of the telegram has been verified. 135 133
On RTL on 7 October, Nuñez confirmed the movement-specific, conditional pause. He described a strong possibility that a stun grenade was involved, not a definitive identification. Franceinfo reported that the suspension followed Emmanuel Macron’s request after the Tuesday government meeting. Tear gas and other munitions fall outside the restriction’s stated scope. 123 130
Even the weapon’s name needs care. The instruction’s launcher-projected “ASSD” conflicts with the specialist Maintien de l’ordre description of Alsetex’s ASSD as hand-thrown only, without tear gas. Le Monde’s 7 October account identifies the suspended launcher round as EF-SON, used with the Cobra launcher. ASSD, EF-SON, tear-gas-containing GM2L and rubber-pellet anti-encirclement grenades are not interchangeable labels. The public record does not resolve the naming discrepancy or establish which model injured the boy. 135 152 149 129
Secondary specifications illustrate the hazard, not the Lens explosion. RTL repeats a specialist ASSD description of approximately 160 decibels at 10 metres and a delay of about 1.5 seconds. The same sound level is reported for EF-SON; its reported range of about 80 metres at a 45-degree firing angle belongs to that launcher round, not hand-thrown ASSD. None of those figures identifies the munition or measures the Lens firing distance. Serious auditory injury and fragments are documented hazards in these descriptions. “Non-lethal” does not mean incapable of permanent injury. 129 152 150
Rights groups question police proportionality toward teenage demonstrators; police unions argue that officers need less-lethal options when confronted with violence. Reported projectiles and warnings deserve investigation. They do not make this boy’s injury inevitable, excuse it in advance or establish a criminal conviction. 4
At Auguste-Béhal, distance learning and a dedicated listening line began on 5 October. Classes resumed partially on 7 October for final-year and post-baccalaureate pupils. That morning, Lille academy rector Sophie Béjean met approximately 200 pupils and their teachers, promising further listening sessions and a return in weeks or months—not a fixed appointment. The pupils’ demands for teachers, replacement cover, supplies and maintained buildings explain the blockades; they cannot explain the grenade injury. 107 189 188 13

As aired 29 lines
- On October 1, we reported police-force inquiries. Now a pupil has lost his left hand. France has withdrawn a stun-grenade capability from high-school protests while investigators establish what happened.
- The restriction has no fixed end date, but it is not a general ban on police grenades. What can the evidence establish about the injury—and what remains unresolved about the police shot?
- A 15-year-old was injured outside Lycée professionnel Auguste-Béhal in Lens, in northern France. He lives in nearby Wingles and was taken to Lille for treatment after the explosion on October 5.
- The injury occurred at about 10:30 local time, with approximately 200 to 250 pupils gathered. The initial deployment account describes stones, fireworks and mortars thrown at local police, followed by a company of CRS riot police. That does not establish that every pupil threw anything, or that the injured boy did.
- The pupils' demands concern more teachers, replacement cover, adequate supplies, maintained buildings and less crowded classrooms. Those grievances explain the school blockades. They cannot establish how a grenade caused this pupil's injury.
- The boy lost one hand, his left—not both hands. The subsequent amputation also means describing the injury simply as lost use of a hand understates the permanent disability.
- He underwent surgery on October 5, received a graft to his right hand, and had wounds to his face and thorax. He was sedated and sleeping extensively afterward, and remained hospitalised on October 7.
- His life was initially described as not in danger. That does not diminish the permanent disability or establish a prognosis for his other injuries. No public medical record, verified rehabilitation plan, discharge date or detailed long-term recovery assessment has been established.
- His mother rejects the pickup explanation and argues that action came only after her son lost his hand. On October 7, she announced that she would file a complaint within hours. Completion of that filing is not established.
- No complaint had yet been filed by the evening of October 6. The next day's announcement changes the family's stated next step; it does not prove that a formal complaint was subsequently lodged.
- Neither a pickup nor an intention to throw the grenade back has been established. A nearby witness rejected both pickup and catching it. Competing explanations also describe a projectile fired toward him or landing on him.
- The preliminary reconstruction identifies warnings to disperse, projectiles directed at CRS officers and burning bins. Police used tear-gas grenades, followed by at least one stun grenade. It does not identify the device that caused the hand injury.
- The precise trajectory and the legality of that particular use of force remain unresolved. The inquiry initially left open whether the boy recovered a grenade that exploded in his hand or whether one landed on him.
- Authenticated amateur footage published on October 7 at 17:16 shows a grenade landing on the ground at two teenagers' feet in a car park. A third teenager bends toward it with a hand extended. The visible frames do not show pickup.
- A CRS line is visible behind them. The third teenager is among about fifteen apparently moving away. He leaves the frame for a few seconds, a detonation is heard, and he is then seen running with the others. The sequence challenges the explanation that the grenade landed directly on his hand, but the missing view prevents it from proving what his hand did before the explosion.
- Investigators' formal receipt of the footage remains unsettled. The directly described position at publication was that the images had not yet reached them. The boy was expected to be interviewed very soon, but no exact date was announced.
- The police watchdog, IGPN, is investigating suspected violence causing permanent disability or mutilation. As of October 7, the CRS officer holding the launcher at the relevant moment had been interviewed as a witness. No Lens-specific charge is established.
- The officer was authorised to use the launcher. That general authorisation does not determine whether this shot was authorised, proportionate and legitimate. Investigators still need to establish whether he was the only officer to launch a stun grenade. A separate officer's formal investigation concerned another pupil's injury in Saint-Ouen-l'Aumône, not this Lens case. Opening the Lens inquiry does not prove an offence.
- The suspension applies only to the high-school protest movement, until the Lens circumstances are clarified. Tear gas and other munitions remain outside its stated scope. The order followed Emmanuel Macron's request after the October 6 government meeting.
- The reported instruction names an Alsetex ASSD grenade projected by launcher. That designation conflicts with technical descriptions of ASSD as hand-thrown only. A public facsimile of the instruction has not been verified, and the naming discrepancy remains unresolved.
- ASSD, EF-SON, GM2L and rubber-pellet anti-encirclement grenades are not interchangeable names. Earlier explanations suggested GM2L or an anti-encirclement grenade; one witness described an explosion consistent with GM2L. The minister described a strong possibility of a stun grenade—not definitive identification of the model responsible.
- The ASSD description gives approximately 160 decibels at 10 metres and a delay of about 1.5 seconds, intended to prevent pickup. The same sound level is reported for EF-SON. It cannot identify which device exploded at Lens.
- The hand-thrown ASSD is described as replacing hand-thrown GM2L after that use was prohibited in July 2021 because of danger to officers. GM2L contains tear gas; this ASSD description does not. The alternative launcher-round description identifies EF-SON, approximately 40 millimetres, used with the Cobra launcher and in service from summer 2025.
- The approximately 80-metre range at 45 degrees, with a precision margin of about 20 metres, belongs to the EF-SON description—not hand-thrown ASSD. It is not evidence of the distance of the Lens shot.
- These are secondary specifications, not independently extracted manufacturer tests or measurements of the explosion. Serious auditory injury and fragments are identified hazards, but the public material does not establish fragment characteristics or wound distances. Calling a weapon non-lethal does not mean it cannot cause permanent injury.
- Auguste-Béhal switched to distance learning and opened a dedicated listening line staffed by education professionals on October 5. A partial return was scheduled for October 7 at 10:00, following discussion with some pupils, for final-year and post-baccalaureate students.
- That morning, Lille academy rector Sophie Béjean met approximately 200 pupils and their teachers for a discussion requested by the education minister. She announced further listening and school-democracy sessions, and a return in a few weeks or months—not a fixed appointment. The visit did not settle pupils' anger or explain their classmate's injury.
- The answer is a permanent injury, a limited restriction and an unfinished investigation. Rights groups question proportionality; police unions defend less-lethal options against violent confrontations. Neither position supplies the missing evidence about this boy or establishes an officer's responsibility.
- The boy's anticipated interview, complete imagery and police deployment record remain consequential evidence. No inquiry completion date or fixed date for lifting the restriction has been announced. The family's complaint still requires confirmation. The boy's left-hand amputation is permanent.
