Update, October 5: This story covers a serious injury that occurred today in Lens during renewed school protests across France. Karmactive first reported the nationwide student blockades and mass arrests on
A 15-year-old student has lost his hand and part of his forearm at a school protest in Lens, northern France, after a police grenade exploded in circumstances that investigators are still determining. The injury has transformed the ongoing dispute over education budget cuts into a direct confrontation over how French riot police handle crowds of minors.
The student was on the perimeter of Lycée professionnel Auguste-Béhal in Lens, in the Pas-de-Calais department, when the incident occurred. He was transported to CHR Lille for treatment. François-Xavier Lauch, the Prefect of Pas-de-Calais, confirmed the incident and the opening of a formal investigation. The Béthune prosecutor’s office opened an investigation, and the IGPN — France’s national police watchdog — has been tasked with examining the proportionality of force used and the exact classification of the munition discharged.
The catastrophic injury of a 15-year-old student in Lens shifts France’s education protests from a policy standoff over budget reforms into an immediate security crisis. Parents and secondary students face rolling school blockades across northern France and Paris this week as student unions call for nationwide action. With the IGPN investigating the use of explosive dispersal grenades near minors, families should anticipate emergency campus closures, heavy perimeter policing, and transit disruptions around major secondary schools.
Police described the device used as a grenade de désencerclement. Its exact classification and the precise circumstances of how it detonated remain under investigation. Its deployment near school perimeters has drawn immediate criticism from human rights groups who argue French police have not adjusted use-of-force guidelines to account for the proximity of minors.
What the IGPN Probe Will Examine
The IGPN investigation will focus on two questions: whether the grenade was used in compliance with operational protocols for crowd management involving underage demonstrators, and whether police established adequate dispersal corridors before deploying explosive munitions. Roughly 200 to 250 students were present at the school perimeter at the time of the incident — a detail that goes directly to the proportionality question investigators must now answer.
What happened in Lens today is the question most people searching this story want answered: a 15-year-old student was struck by a police blast grenade at a school protest, lost his hand and part of his forearm, and is now in hospital in Lille. The prefecture and the IGPN have opened formal inquiries.
Whether French high schools close nationally in the coming days depends largely on how the government responds to both the injury and the IGPN findings. Check back for updates as investigators release preliminary findings.
