A 15-year-old teenager lost his hand on Monday after a police officer reportedly threw a deafening grenade near a high school in Lens. The incident occurred during a demonstration close to the Auguste Béhal high school. The exact circumstances remain unclear, with an investigation by the IGPN (Independent Police Oversight Authority) underway to determine whether the teenager picked up the grenade or if it landed on him. One report described the grenade as "deafening," while another source initially mentioned a disengagement grenade. The teenager has reportedly lost the use of his left hand and "two fingers of his right hand," with doctors considering whether amputation at the wrist or elbow may be necessary. Some young people continued to protest on Tuesday, this time with labor unions. Others now express fear of police violence. A teacher at the Auguste Béhal high school, where the injured student is enrolled, said the school closed on Monday afternoon and Tuesday, with a support and listening cell set up for affected students. The teacher described the atmosphere as one of "shock, consternation, and anger," noting that the student was a sophomore in vocational training and that his professional future would be "complicated" after losing the use of a hand. The National Police Inspection General was formally charged with "violence resulting in disfigurement and permanent disability," according to the prosecutor in Béthune. The police were reportedly overarmed during the incident, with one witness estimating that there were about 50 to 60 CRS (Républicaine de Sécurité) officers facing 150 to 200 students. According to a police source, the teenager was injured by "a deafening grenade," while a union source initially mentioned a disengagement grenade. The Interior Minister, Laurent Nuñez, stated that at least one Molotov cocktail was thrown by protesters. The police have faced criticism for what some describe as a disproportionate response to isolated incidents. Juliette Beigelman, a lawyer and member of the syndicat des avocats de France (French Bar Association), noted that while there are serious incidents during the protests, the response by law enforcement is "disproportionnée" (disproportionate) and "venimeuse" (venomous). A 16-year-old student, Mike Ryan, described the incident as "scary," saying that "we feel like we're at war." Another student, Walid, stated that high school students must "continue" to make their demands heard, adding that "it's not by tearing off our hands, feet or other parts of our bodies that they will stop us from doing what we are doing." The police have faced multiple complaints, with the force being charged for the 10th time since the start of the mobilization. A 16-year-old student lost the use of an eye during a protest, with the prosecutor suggesting the injury was compatible with a LBD (Lanceur de Balle de Défense) shot, a type of non-lethal weapon. Another police officer has filed a complaint for a filmed attempted drowning during a mobilization. The CGT union, which represents workers, promised to protect its members, while the Interior Minister, Laurent Núñez, said he would respond to the situation before a parliamentary commission.
