A lockdown was in place on Friday at Cégep Saint-Jean-Sur-Richelieu after a man was reported inside the cégep exhibiting “suspicious” behaviour. Police created a security perimeter and restricted access to the school, and students were instructed to barricade themselves in a close room and to keep the lights off. CTV News and City News report that a 19-year-old male suspect wearing a “bulletproof vest” and a female minor have been arrested. The lockdown lifted shortly after noon and all activities at the cégep were canceled for the rest of the day.
