Police are investigating after a man punched two teens on a SkyTrain last month.

Metro Vancouver Transit Police say a man allegedly punched two teenagers on Oct. 4 at about 12:15 p.m. on a train between Moody Centre to Coquitlam Central stations.

“The suspect became enraged when he believed the two victims, 14- and 16-year-old boys, had been staring at him,” police said in a statement to CTV News.

One victim suffered a bruised eye while the other teen’s head slammed into the wall of the train.

The suspect is described as a white male with a slender build, black hair and dark facial hair. He was wearing a black and grey hoodie, grey pants, runners and dark sunglasses.
