Peel police say they are looking for three men after a "vicious" assault on a man with autism at a Mississauga bus terminal.

The man, 29, originally from Nova Scotia, was sitting on the stairs on the lower level of the Square One bus terminal, 200 Rathburn Rd. W., on Tuesday at about 10:45 p.m. That's when three men walked down the steps and approached the man, Peel Regional Police said in a news release on Wednesday.

The trio surrounded the victim, with one grabbing his jacket. All three punched and kicked him repeatedly. Video footage released by police shows the suspects walking away, with one glancing around to see if anyone was looking.

Police said the man was taken to hospital with serious but non-life threatening injuries.

The video also shows a male bystander walking near the incident toward a nearby escalator.

All three suspects are believed to be South Asian males and five feet, 10 inches tall. Two have light complexions with thin builds, while one has a medium complexion with a medium build.
