A “random” stabbing on a TTC bus near Victoria Park and Danforth Avenues Wednesday night left a man with “life-altering” injuries, police say.

Const. David Hopkinson, of Toronto police, believes the stabbing was random.

“We are not aware of any altercation between the two,” he said.

Police got the call reporting an incident on the northbound 12A bus at around 5:45 p.m.

A suspect armed with scissors fled the scene, only to be tracked down by police “a short distance away” without incident, Const. Michelle Flannery told the Star by email.

Paramedics said that the victim was transported to hospital in “stable condition.”
