The latest in a string of violent incidents on the TTC has seen a 16-year-old boy sustain severe injuries after he was stabbed on a bus.
 The Toronto Police Service called to Bloor Street West and Old Mill Trail at around 4 p.m. on January 25.
When they arrived, officers found a teenage victim with stab wounds to his torso and legs. He was transported to a trauma centre with serious but non-life-threatening injuries, Toronto paramedics said.
TPS describes the suspect, who is still outstanding, as a man in his 20’s wearing a blue mask and a black jacket with a medium build.
“Our thoughts are with the victim in this attack,” the TTC tweeted. “As always, we’ll give police our full support as they investigate, including video and witness statements.”
The stabbing is the fifth reported attack on the city’s transit system since Saturday. Earlier on Wednesday, two TTC employees were allegedly chased by a person wielding a syringe at Dundas Station. Police have taken a suspect into custody.
On January 24, a woman was stabbed multiple times in the face and head while riding a TTC streetcar.
On Monday, two TTC employees were attacked on a bus in Scarborough in what police described as a “despicable” swarming-style assault. Four 13-year-old boys have been arrested for the assault.
Before Wednesday’s stabbing, TTC CEO Rick Leary said the number of violent incidents is alarming and vowed to take immediate action.
Police are asking anyone with information on the latest stabbing to reach out to investigators at  416-808-2222.
