The Toronto Police Service has made yet another arrest involving an unprovoked assault on the TTC. 

On March 23, just after 9 a.m., police were called to Bathurst subway station following reports of an assault. 

It's alleged that a 15-year-old boy was on the escalator heading up to the street level, when a man who was walking in front of him turned around and punched the boy. 

Police said the attack was made "without provocation," representing yet another random and unprovoked crime that's taken place on the transit system over the past few months. 

The suspect has since been identified as 33-year-old Justin Corbett of Toronto, and he has been charged with assault causing bodily harm. 

It joins a growing list of incidents on the TTC.

On Thursday, police received reports of another person with a knife at St. George subway station just after 9 a.m. 

The man was reportedly carrying a razor blade in his hand and pacing back and forth throughout the station. Luckily, no injuries were reported but the man managed to flee the area prior to police arrival. 

Anyone with information is asked to contact police at 416-808-1400, Crime Stoppers anonymously at 416-222-TIPS (8477), or at www.222tips.com.
