Police have charged a 24-year-old Toronto man with second-degree murder in connection with the death of another man on Gloucester Street overnight.

Police were called to Gloucester near Yonge Street shortly after midnight for "unknown trouble" and located the victim suffering from "obvious signs of trauma," according to a news release.

The victim, 42-year-old Ramsey Whitefish, was pronounced dead at the scene.

Earlier Wednesday, Toronto Police Homicide Det. Paul Worden said investigators had identified a "person of interest" who was "very close" to the victim and asked anyone who was in the area between 11:30 p.m. and midnight to come forward. Investigators canvassed Gloucester Street for surveillance video.

Worden said the victim did not have a fixed address, but frequented the downtown core and was known to police.

"He had a sleeping bag with him and he was wearing a fedora" at the time of his death, Worden said.

He confirmed that a gun was not used in the incident.

A post-mortem is scheduled for Thursday.

On Wednesday, police arrested and charged Trevor Severin, 24, with second-degree murder. Severin is scheduled to appear at College Park court on Thursday.
