GO train station stabbing: Police release photo of suspect

Toronto police are appealing to the public for help identifying a suspect who allegedly stabbed and robbed a teenager at a GO train station on Wednesday evening. 

According to police, the 18-year-old victim was awaiting a train at Eglinton Station, near Eglinton Avenue and Bellamy Road, at around 5:30 p.m. when he was allegedly approached by a man who demanded he hand over a gold chain.

The victim refused and a fight occurred, during which the suspect stabbed the teen multiple times and stole his chain, police say. 

A brief foot chase ensued, but upon realizing he had been wounded, the victim returned to the GO station, police say. He was later transported to hospital suffering from several stab wounds and a collapsed lung. 

An image of the suspect was captured on a security camera nearby where the incident occurred. He's described as about 25 years old, six feet tall and about 175 pounds, with black hair and a moustache.

He was wearing a black, varsity jacket over a black, hooded sweater, blue jeans and a baseball cap.

Anyone with information is asked to contact police or Crime Stoppers.
