A 16-year-old high school student from the Paul-Hazard high school in Armentières (North) was arrested and placed in police custody this Tuesday morning. He had made threats against his philosophy teacher, during a discussion with comrades on a social network.

The police intervened quickly and set up a security system around the school. The teenager, presumed innocent, was unknown to the judicial services. All these events recall the attack in Arras (Pas-de-Calais), where Dominique Bernard was killed by a radicalized former student.
