The clip shows how a typical commute can turn ugly in the blink of an eye.

The assailant — since identified by Toronto Police as Edith Frayne, 45, of Toronto — wasn't even looking in the direction of the victim when, suddenly, she pivoted 180 degrees and lunged seemingly at random towards her.

Mayor John Tory spoke out against the unprovoked subway pushing, calling it "shocking" and congratulating the police on their investigation.

Thank you to@TorontoPolice, the TTC and the public for good cooperation that led to an arrest in the shocking subway platform attack. Once again, great police work and effort put towards a very urgent case.
