3 Killed in Toronto Crossbow Attack

— -- Three people were killed in a crossbow attack Thursday in Toronto, according to police.

Just before 1 p.m., police officers responded to a call of an individual stabbed near Lawndale Road and Argo Road, Toronto Police Service spokesperson David Hopkinson told ABC News. Upon arriving, officers found two other victims suffering from what appears to be wounds from a crossbow.

An ambulance was sent to the scene after the vital signs of the victims were deemed "absent," Hopkinson said. All three were pronounced dead at the scene.

One person has been taken into custody. Police are treating the case as a homicide, Hopkinson said.

Details on the individual in custody or a possible relationship between the victims and the individual were not disclosed by police.
