TORONTO, Ont. – Toronto police are seeking witnesses after two men were shot in northwest Toronto Tuesday, a few kilometres away from a fatal shooting earlier.

Investigators said a 17-year-old boy was shot in the head and a 23-year-old man suffered gunshot wounds to his groin and shoulder shortly after 8 p.m. on Falstaff Avenue near Jane Street and Hwy. 401.

Both men were taken to hospital, where the boy is in serious condition.

Police are reviewing surveillance video.

Investigators said several people ran from the area when the shooting occurred and are urging them to contact police.

There is no evidence linking the incident to the deadly shooting of a man earlier Tuesday.
