Police Grenade Controversy Explained: How a Teenager Lost His Hand and Why France Is Divided

A 15-year-old high school student lost his hand during a protest in northern France. A 14-year-old lost several teeth. Another student lost the use of an eye. Within days, the government had suspended one of the police’s riot-control weapons, and the country was fighting over who was responsible.

The police grenade controversy has become the most explosive part of the 2026 France protests, because it is about children and because the facts are still disputed. This page explains what is known, what is claimed, and what is still unanswered.

For the wider crisis, see our France protests guide and the full timeline.

What Happened in Lens

On Monday, October 5, a 15-year-old boy was badly hurt during a clash between students and riot police in Lens, in northern France. His hand was blown off. Reports at the time said it happened after police fired a stun grenade.

What happened next is where the stories split.

• The authorities’ version: Officials have said that the student picked up the grenade before it detonated, according to UPI. Early reports, cited on Wikipedia’s blast-ball page, also suggested he was holding the device when it exploded.
• The witnesses’ version: Other witnesses said he was hit directly by the grenade.

Neither account has been confirmed in the reports we reviewed. The investigation is ongoing, and anyone writing about this as settled is getting ahead of the evidence.

Not an Isolated Case

Lens is the worst case, but it is not the only one. The reported incidents include:

• A 14-year-old in northwest Paris was hit in the face by a tear gas grenade at such close range that he lost several teeth. An officer was charged over this on Tuesday, October 6.
• A student who lost the use of an eye in a protest-related incident, according to Interior Minister Laurent Nuñez.
• Teenagers with what human rights lawyers described as “warlike injuries,” according to Al Jazeera’s reporting before October 17.

By October 8, Prime Minister Sébastien Lecornu said 215 students and 89 teachers had been injured since September 28, alongside 761 police officers and gendarmes.

What the Government Did

On Wednesday, October 7, Nuñez told RTL radio he was suspending the use of stun grenades at high school protests. He said the suspension applied only to those protests and would last until the facts of the incident were clarified.

He also said the police watchdog IGPN had opened 18 investigations into whether the police response was proportionate. That is up from ten investigations reported two days earlier.

Macron asked police to show empathy and more “pedagogy” toward student protesters, and the interior minister banned one type of police grenade, according to CNN’s reporting.

What the Government Denies

The government has refused to accept the “repression” label. Lecornu said no order had been given to crack down on teenage protesters, and he rejected claims that police are racist. Nuñez called the police response proportionate in almost all cases. The government also says the protest movement has been hijacked by outsiders and morphed into urban violence.

Ministers point to the violence on the other side. Lecornu has said more than 900 police officers have been injured since the protests began, and that this is among the most violent unrest in decades.

What Critics Say

Critics say the suspension came late. Manuel Bompard of the hard-left France Unbowed said it took several children being maimed for life before Nuñez gave up using grenades against high school students. Protesters say it makes no sense to use force on minors, and student unions have made police violence one of their core demands alongside funding.

Yellow Vest veteran Jérôme Rodrigues, who lost an eye to a rubber-ball grenade in 2019, said the students are facing the same police “repression” the Yellow Vests experienced. That link between 2018-2019 and 2026 is a big reason the old movement is coming back.

The Suspension Has Limits

This is the part many readers miss. The suspension covered student protests, and it was described as temporary. It was not a ban on the weapon, and it did not apply to every protest.

Before the October 17 protests, Nuñez said that if clashes broke out, all types of “intermediate weapons” could be used, according to Reuters. The reports we reviewed do not say which weapons were actually used on October 17, so we can’t tell you that. What we can say is that police used tear gas and water cannons in Paris that day.

The Questions Nobody Has Answered

1. What exactly happened in Lens? Did the boy pick up the grenade, or was he hit? The two accounts are very different, and the answer decides who is responsible.
2. Will the 18 investigations lead anywhere? One officer has been charged in the tooth case. We have not seen charges in the Lens case.
3. Will the suspension be extended? It was tied to establishing the facts, not to a fixed date.
4. Why were so many minors on the front line? The Justice Ministry said 87% of the 5,060 people arrested by October 6 were minors.

Why This Matters

The grenade controversy is not a side story. It changed the movement. What started as a complaint about teachers and buildings picked up a second grievance: that the state is hurting its own children. That is the grievance that pulled the Yellow Vests back in, and it is the one the government finds hardest to answer.

If the investigations confirm police misconduct, it will damage the government’s position. If they show the boy picked up the grenade himself, it will damage the protesters’ account. Either way, a teenager has lost his hand, and France is still arguing about why.

We will update this page as the investigations progress.
