A teenager is facing four charges after a student was stabbed seven times inside a west-end Toronto high school on Thursday morning.

The attack happened at about 9:30 a.m. at Humberside Collegiate Institute, on Quebec Avenue near Keele and Dundas Streets.

Police say a 17-year-old boy in Grade 12 student was stabbed by another boy, a 16-year-old Grade 10 student. The bloodied victim stumbled down the hall to the office for help. He was taken to hospital with non-life-threatening injuries.

The incident triggered a lockdown, and police were called. Officers scoured the school and arrested the young suspect there a short time later.

The lockdown ended after about 90 minutes, school officials said.

Police have not yet released a motive for the attack, but the school principal, June Stavropoulos, said the victim had been in a fight.

The 16-year-old suspect cannot be named because of his age. He was charged with:

  • aggravated assault;
  • assault with a weapon;
  • weapons dangerous; and
  • carrying a concealed weapon.
