Peel Regional Police have arrested a 16-year-old girl after officers allege she encouraged fellow students to bring weapons to school on Monday.
Police said they became aware of the message, which was posted to Snapchat, on Sunday.
Investigators said the girl wanted the weapons to be brought to St. Edmund Campion Secondary School in Brampton on Monday so the school day would be disrupted.
