A 20-year-old man accused of stabbing a 16-year-old student at a high school in La Courneuve has been charged with attempted voluntary homicide, the prosecution said. The suspect, who admitted attacking the teenager with a knife, was placed under judicial supervision rather than remanded in custody. The case was opened after the stabbing on Thursday in the Seine-Saint-Denis city of La Courneuve. Prosecutors in Bobigny had asked for detention while the case is investigated, but the court opted for judicial control. The measures include an order not to appear in Seine-Saint-Denis. The 20-year-old is said to have admitted the attack while disputing that he intended to kill. Prosecutors said he gave contradictory explanations, including claims about feeling threatened. He also raised mental health issues multiple times during proceedings, with prosecutors noting that a possible impairment of judgment was considered due to bipolar-type troubles. That point will be assessed as part of the investigation. The legal action covers the stabbing of the 16-year-old, who was injured in the chest, and also events involving two other minors who were not hit. The investigation additionally concerns carrying a Category D weapon. The victim left the emergency department the same day after receiving two stitches. His total inability to work was set at five days. The incident took place during a blocking of the Denis Papin vocational high school linked to the nationwide student movement that began in mid-September. Police and prosecutors will continue working to establish the exact course of the altercation and the circumstances leading to the use of the knife. The suspect remains out of custody under judicial supervision as the judicial investigation continues.
