A Grade 11 student was treated and released from hospital after he was stabbed several times during a hallway fight at a Brampton high school Wednesday.

Judith Nyman Secondary School went into lockdown just after the stabbing, which occurred around 10 a.m.

The lockdown was lifted about 90 minutes later after Peel police tactical officers determined none of the culprits was still on the scene.

Const. George Tudos said investigators aren’t certain what was used to inflict the stab wounds.

“There was an altercation shortly before,” Tudos said outside the high school, on Williams Parkway near Bramalea Road. “He suffered more than one wound.”

Police found the injured student lying in a hallway.

“He was conscious and breathing,” Tudos said.

Police don’t know if the assailants attend the school or what their relationship is with the victim.

“We have some witnesses and we are looking for more,” Tudos said.

Students said a teacher heard a commotion in the hallway. When the teacher went to investigate, she saw a boy bleeding profusely from his arm.

Police haven’t released any descriptions of the suspects. It’s also unknown if the weapon has been found.
