Hooded individuals armed with Molotov cocktails attacked the Cachan comprehensive high school, in Val-de-Marne, this Tuesday morning. A 17-year-old boy was arrested, but the circumstances surrounding this outburst of violence still remain unclear.

Security will be reinforced around the establishment, announced the Paris police prefect, Laurent Nuñez. For several weeks, teachers have been denouncing the unsanitary conditions of the building. But for this professor, the violent actions of the morning are not directly linked to this discontent.
