Toronto police say one man is dead and a teenage boy is injured after a shooting outside a high school in the city's east end.

Police say on Twitter that officers responded to reports of a shooting at Woburn Collegiate Institute around 3:20 p.m., prompting the school to go into lockdown.

They say one man was taken to hospital and was later pronounced dead there.

A teenage boy was also taken to hospital after he was injured, but there were no details on his condition.

Police say a suspect fled the area.

They say students are exiting the school on the east side with the assistance of police and parents can pick up their children.
