The TTC says it has handed surveillance footage over to Toronto police after a man was caught on video tossing a custodian’s bucket of mop water on a woman at Lawrence East Station.

A brief clip of the incident was originally posted to Instagram by @Starzto on Tuesday night. The clip has been viewed nearly 7,000 times.

The video appears to show a woman arguing with a man. At one point, the woman flicks water from the bucket at the man. Seconds later he grabs the bucket and dumps its contents over her head before fleeing down a flight of stairs.

A TTC employee is visible in the video, but doesn’t intervene.

The TTC tells CityNews it is cooperating with police, who are treating it as an assault with a weapon.

The transit agency launched a new safety smartphone app on Wednesday to combat harassment and improve customer safety. Through the app, customers can discreetly report incidents.
