The Cachan comprehensive high school, in Val-de-Marne, was the target, this Tuesday, March 5, of several dozen hooded and armed individuals. A municipal police vehicle as well as a car belonging to the town hall were stoned and then overturned.

This Wednesday, the return to school is possible, but at the cost of a significant police force. The students of the polytechnic high school declared to Europe 1 that they had never seen such a security system, nor had they witnessed such violence in front of their high school.
