TORONTO – The province’s Special Investigations Unit is probing a fatal shooting on a TTC streetcar early Saturday morning.

A man died in hospital after he was shot during a clash with police just after midnight at Dundas Street West and Bellwoods Avenue, west of Bathurst Street.

On Monday, the SIU identified the victim as Sammy Yatim, 18. He was identified by friends and family on Sunday.

A bystander told CityNews Yatim was armed with a knife and police ordered him to drop it while pointing their guns at him.

The witness — who did not want his name used — said officers fired several rounds and then started performing CPR.

He also said two people were taken to hospital in separate ambulances. No passengers were on the streetcar at the time of the shooting.

Yatim was rushed to St. Michael’s Hospital with multiple gunshot wounds, but later died, the SIU says. A Taser was also used, the agency says.
