Peel police have identified a man stabbed to death in Mississauga early Tuesday.

Christopher Birrell, 24, of no fixed address, died at the scene, police said in a news release.

Const. Sarah Patton, spokesperson for Peel police, said two men were seen in "some sort of altercation" in the area of Aquinas Avenue and Sebastien Drive at 2:20 a.m.

One of the men fell to the ground, and the other left the scene on foot.

A passerby reported the fight to police.

When officers arrived, they found Birrell on the ground in the middle of Sebastien Drive, with "obvious signs of trauma."

Police said later that he was suffering from what appeared to be stab wounds.

"The circumstances surrounding his death are still under investigation," Patten told CBC Toronto.

No further description of the other man was available at the time of the interview.

Peel's homicide unit has taken over the investigation.

Officers spent the morning speaking to neighbours in the area and searching for any security camera video.

Anyone with potentially valuable information for police is asked to contact investigators or leave an anonymous tip with Crime Stoppers.
