A 24-year-old Maryland man who was in Toronto for a bachelor party died shortly after being severely beaten near College and Bathurst Streets early on Saturday, Toronto police say.

Det. Rob North, spokesperson for the Toronto Police Service's Homicide Squad, said the assault was an unprovoked attack on the man. He was found suffering from severe trauma south of College Street on Manning Avenue.

North said police received a call about the assault at around 2:25 a.m.

He said the victim and his friends, most of them visiting from the U.S., left the Blnd Tger nightclub on 559 College St. and were approached by another group of seven to nine men. The victim was separated from his friends, punched once in the head, knocked to the ground and kicked in the head repeatedly.

"This was a completely unprovoked attack," North said.

The group fled south on Manning Avenue towards Dundas Street West.

Toronto paramedics tried to perform first aid on the man, but he succumbed to his injuries in the ambulance and was pronounced dead en route to hospital.

Police are notifying next of kin.

North said police are looking for two suspects. The first is described as a white man, 26 to 27 years old, short black hair, wearing a black top, black pants, with a slim build.

The second suspect is described as a black man, 26 to 27 years old, with a large build and a full beard, "looking like a football player," wearing a black fitted top and black skinny jeans.

Police initially said they were looking for a third suspect, a man in a red baseball cap who was a member of the group that included the attackers. Now, they say they only want to speak to that man.

Earlier, Const. Craig Brister of the Toronto police said one of the men with the victim was a U.S. serviceman.

Anyone with information is urged to call Toronto Police Service's 14 Division or Crime Stoppers at 416-222-TIPS (8477).​
