Man charged in Canada bus knifing

Canadian police have charged a man over a knife attack on a bus in northern Ontario that left a fellow passenger needing hospital treatment.

Other passengers have queried why police put the alleged attacker, David Roberts, on the Greyhound bus in the first place.

Officers said they helped him get a bus ticket home after earlier dealing with him for a public disturbance.

Concerns about security were raised after a murder on a bus in July.

Sunday's incident happened about 16km (10 miles) east of White River in Ontario as the bus was travelling from Toronto to its destination, Winnipeg.

Witnesses said there was a commotion at the back of the vehicle and they saw a man clutching his chest in pain.

A 20-year-old man was taken to hospital for what police described as "non life-threatening injuries".

Mr Roberts has been charged with aggravated assault and breach of probation.

Police officers said Mr Roberts and the victim did not appear to know one another.

Ontario police have confirmed that Mr Roberts was involved in a public disturbance on Sunday morning.

Mr Roberts reportedly asked to be taken to hospital for psychological help, where he was examined and deemed not to be a threat, according to Canadian media.

Police then helped him get a bus ticket, as he expressed a strong desire to go home, Sgt Larry Ross of the Wawa municipal police told CBC News.

The suspected stabbing comes less than two months after a man was beheaded on a Greyound bus.

Vince Weiguang Li has been charged with second-degree murder and has been undergoing psychiatric tests to see if he is fit to stand trial.

Greyhound and the government's transport department, Transport Canada, are expected to meet this week to talk about ways to improve bus safety, CBC News reports.
