A 16-year-old high school student was arrested Tuesday morning in Armentières (North) after threatening to slit the throat of his philosophy teacher. This teenager, unknown to the justice system, had made these threats on Monday to his comrades on this network, said one of his sources.

It was then reported on the Pharos platform, a government site for reporting illegal content online. He was arrested early Tuesday morning, then placed in police custody, according to police sources.
