Subway service has resumed along the University-Spadina line, but trains are bypassing Osgoode station as police continue to investigate the shooting of a 19-year-old man earlier today.

Police are looking for a black man, about 6' to 6'2" tall and roughly 185 lbs., who was last seen wearing black pants, a black parka with a fur-trimmed hood, and a black Blue Jays ball cap bearing the team's new logo. It is unclear at this time whether he knew the victim.

At a press conference this afternoon, Supt. Hugh Ferguson said the man that police had previously questioned is not the shooter, but may have been part of the group travelling with the suspect.

The victim, who was known to police, was travelling from the north end of the city. Just before 11 a.m., a fight broke out between a group of people who were exiting the subway.

At least three shots were fired on the central platform and police say the fight continued to the mezzanine level before the victim collapsed.

When police arrived, they found the19-year-old man suffering from two gunshot wounds, one to his stomach and one to his thigh. Ferguson said one witness, a woman, stayed with the victim after he was shot.

He was taken to St. Michael's Hospital with serious but non-life-threatening injuries.

Mayor David Miller, who is in Los Angeles promoting Toronto's film and television industry, said in a statement he was "shocked and alarmed" by the brazen daytime attack.

"Toronto is, by any standard, the safest large city in North America and the TTC is a safe public transit system. But incidents like this remind us that we must remain vigilant when it comes to public safety."

Members of the Toronto Police Emergency Task Force were called in to search the subway tunnel for more suspects.

Carrie Wiebe had just made her way off the subway car when she heard three gunshots. "As soon as the doors opened we got off and then there were shots," she said.

Wiebe, who was on her way to a concert at the Canadian Opera Company, said she first thought the sounds came from construction activity.

By the time she realized what had happened, several people were running out of the station and toward the southwest corner of University Ave.

Police are urging anyone who was on a subway train at the time of the shooting to call 52 Division at 416-808-5201.
