A man found with serious injuries in an apartment in North York on Saturday has been pronounced dead, Toronto paramedics say.

Police said they were called to an apartment on Wakunda Place near O’Connor Drive after 9:30 p.m. on Saturday for a report of an unconscious male.

They arrived to find a man suffering very serious injuries. He was without vital signs when they arrived.

He was pronounced dead at the scene a short time later.

A man who lived on the same floor as the victim said neighbours knocked on his door to tell him that something had happened to “Henry” down the hall.

He went to the victim’s apartment and saw the man on the ground unconscious.

“I looked in the doorway; I saw his body full of blood. I don’t know whether it was a stabbing but there was a lot of blood.”

The man said he then called 911 and spoke to investigators.

"He was a nice guy, I don't know why someone would (kill) him."

Other residents of the building said the victim was a man in his 50s.

Investigators are treating the death as suspicious.
