Overview
- The proviseur of Lycée Saint‑Michel found a backpack in the school hall on Monday that contained a firearm with a folding stock and scope, two silencers, and 47 cartridges.
- School staff alerted police, officers recovered the weapon and munitions, and the Brigade de recherche et d’intervention secured the site while families were informed and no students were present.
- Investigators identified and arrested an agent technique who worked for the school as a contractor and is registered as a sport shooter; he was placed in garde à vue after being intercepted leaving his building.
- Police sources say the suspect is already known to authorities for prior threats involving a weapon and that he reportedly disabled the school alarm to deposit the bag in a spot not covered by video surveillance.
- Probes now focus on establishing motive, how the items were brought into the lycée, and whether the school's alarm and camera gaps require changes to contractors and security procedures.
