Police are investigating a stabbing aboard a Greyhound bus bound for Winnipeg, an incident in which a young man was attacked by another passenger as the vehicle travelled through northern Ontario.

The man who was stabbed is believed to be in his 20s. He was taken to hospital Sunday afternoon with minor injuries, the Sault Star newspaper reported.

Police arrested a 28-year-old man near the town of White River, about 300 kilometres north of Sault Ste. Marie, Ont., shortly after the bus driver let him get off at the side of the highway.

"I can confirm that an incident did occur aboard one of our buses," said Greyhound spokesperson Abby Wambaugh, speaking from Dallas, Texas.

"The incident occurred 10 miles [16 kilometres] east of White River," she said. "The bus originated in Toronto and was headed for its final destination of Winnipeg."

Wambaugh said the company is "co-operating fully" with Ontario Provincial Police in the investigation.

Another bus was provided for the 13 remaining passengers to continue on their trip.

The incident comes less than two months after a Greyhound passenger beheaded Tim McLean, a 22-year-old man from Winnipeg, sparking questions about security on buses.

Vince Weiguang Li, 40, is charged with second-degree murder and is undergoing a psychiatric evaluation to see whether he is fit to stand trial. He's scheduled to appear in court Oct. 6.
