The victim, though severely injured, was reportedly treated in serious but not life-threatening condition.

Police say that, with the assistance of the community, the suspect was quickly apprehended and charged with attempted murder and several weapons-related offences.

Valdez appeared in court virtually at Old City Hall on Wednesday morning to face her charges.

The attack joins a growing list of violent incidents on the TTC in recent weeks, a wave of crime that has left Toronto residents feeling uneasy on public transit and even just walking down the street.

Unprovoked attacks are proving another problem on the rise in Toronto, including the horrifying murder of Ken Lee by eight unknown teenage girls in late 2022, and, more recently, the killing of an elderly woman on a busy stretch of Yonge Street.

The chaos continued on Wednesday, when two TTC workers were randomly chased by an attacker wielding a syringe at Dundas subway station.
