TORONTO -- Police are looking for a subway slasher after a man was stabbed in a random attack on board a subway train Wednesday night.

The train was travelling south after 10 p.m. when a man began harassing passengers, police said.

One man stood up and was stabbed in the neck, suffering serious but non-life-threatening injuries.
"The attack was completely unprovoked," Const. Tony Vella said.

The passenger assistance alarm was activated and the train was stopped at Davisville subway station, where the suspect fled the scene, he said.

The suspect is described black, 30 to 32 years old, and six feet to 6-foot-2 in height with a thin build.

He was wearing a black tuque, black pants, black jacket and a hoodie and was carrying a white plastic bag. Police have released surveillance images of the man.

"We are working closely with (transit) officials, doing everything possible to find this man," Vella said. "We are asking for the public's assistance, if they have any information in the case they need to contact police."
