SIU called to scene of Agincourt Mall shooting

Ontario's Special Investigations Unit is investigating after a shooting today at Toronto's Agincourt Mall, which occurred after police responded to a report that a man was harming himself with a butcher's knife.

Toronto police say they received a call about the man who was behind a Walmart at the mall, which is located in the Kennedy Road and Sheppard Avenue East area.

Police say the SIU, which investigates all incidents involving police in Ontario in which death or serious injury occur, has invoked its mandate.

Paramedics were called to the scene and the man was taken to hospital.
