There was a heavy police presence in and around a Mississauga school Monday (Dec. 3) after a threat to a student’s life was made online.

The incident was reported to Peel Regional Police around 10 a.m. by a staff member at Clarkson Secondary School on Bromsgrove Road, in the area of Royal Windsor Drive and Winston Churchill Boulevard.

Peel Const. Danny Marttini said the student received the threat online and then went to a staff member essentially saying, “I’m concerned for my well-being,” she said.

Heavily-armed tactical officers were at the school searching for a suspect. It's not known whether a weapon was indicated in the online threat.
