Police are investigating another unprovoked attack on the TTC. The latest happened late Tuesday night at St. George station.

A 30-year-old man received serious injuries after he was stabbed in the neck while sitting on the platform around 11:30 p.m. Police say the crime appears to have come out of the blue. The suspect fled. He’s white, in his 20’s with short blond hair and a neck tattoo.

Just three days ago, a woman pushed another woman off the platform at Bloor-Yonge station onto the tracks.

She survived and a 45-year-old woman is now charged with attempted murder.

Meantime, Toronto’s Transit Commission says it will deploy more special constables after unprovoked these unprovoked attacks.

“We have on a daily basis about 40 special constables patrolling the TTC and when things like this happen on the subway system, we will then look at that and use it to guide our tactical deployment,” said TTC spokesperson Stuart Green. “So we’ll have more special constables available in the subway system specifically over the next few days.”

Police report a third incident happened eight days ago at Pioneer Village Station that involved a suspect choking a man unconscious and robbing him.
