Police have arrested two suspects in the shooting of a student at a Toronto high school.

Const. Wendy Drummond said Wednesday that an adult and one young person, who cannot be identified under Canada's criminal laws, have been arrested after a 16-year-old boy was shot in the abdomen on Tuesday.

He was shot during a fight on the grounds of Bendale Business and Technical Institute in Toronto.

The shooting prompted a tense 2 1/2-hour lockdown that left parents anxiously waiting for confirmation that their children were safe.

The victim was rushed to hospital in critical condition. Police have not yet updated his status.
