Warning: The video below shows a violent attack and may be disturbing to some viewers.

Police in Mississauga, Ont., have released a video of three suspects wanted in connection with a “vicious assault” on a man with autism.

The video shows the victim, 29, sitting on a stair in a shopping centre bus terminal. He appears to be putting on or removing inline skates when three males walk down the stairs and attack him.

One of the males starts by punching the victim, after which a second male kicks the victim and a third male joins in with kicks and punches.

The victim was taken to a local hospital with “serious but non-life-threatening injuries,” according to Peel Regional Police.

The violent assault happened at the Square One Shopping Centre at approximately 10:45 p.m. on Tuesday, according to police.

Peel Regional Police Const. Bancroft Wright told Toronto’s CP24 that the victim was treated in hospital for a broken nose and multiple lacerations.

Wright said it’s not clear what precipitated the attack and police are hoping that the video will prompt witnesses to come forward or the suspects to turn themselves in.

“What you don’t see in the clip of the video is that to the immediate right is an escalator that goes up and there were a number of individuals that were taking the escalator at that point,” Wright said.

“That’s the escalator they fled by and then from there they went in separate directions,” he added.

The three suspects are described by police as South Asian males, all about 5’10” tall.

One has a thin build, a short dark beard and straight black hair, police say. He was wearing a black T-shirt with a red Air Jordan logo and white lettering, black track pants and black shoes.

The second suspect was clean-shaven and wearing a black jacket with a grey horizontal stripe across the chest and a grey vertical stripe along the hood, black track pants, and black shoes, according to police.

The third suspect is described as having a medium build, was unshaven and was wearing a black hoodie with a Nike logo on the front and white lettering along the sleeves, with black track pants and black shoes.
