Heavily-armed tactical officers and police dogs responded in large numbers near a Brampton high school Thursday afternoon (May 31) after a stabbing sent a teenaged boy to hospital with serious injuries.

The incident occurred just after 1 p.m. across the street from Notre Dame Catholic Secondary School, in the area of Kennedy Road North and Bovaird Drive East.

The school was in lockdown, meaning students and staff in the building took refuge in a secure location such as offices or classrooms.

Nearby Kennedy Road North Daycare, as well as St. Leonard, St. Agnes Heart Lake Secondary and Conestoga schools, as well as Oxford Learning Centre, were all in hold and secure, meaning no one can enter or leave the building and all doors must remain locked.

All lockdown and hold and secure orders have since been lifted.

Police are hunting as many as six teenaged suspects.

School resource officers and uniform officers are on scene, according to Peel Const. Iryna Yashnyk.

The victim, a 16-year-old boy, has gone to hospital with serious injuries but is expected to survive.

Several students and residents in the area took to social media, with one student identified as Carey writing on Instagram, “We're all scared. This has never happened here before.”

This is the second time in two days a stabbing has occurred in a Brampton neighbourhood. On Wednesday, a 26-year-old woman was rushed to hospital after she was knifed at an apartment building on McLaughlin Road. She is expected to survive.
