One person has been seriously injured after a late-night stabbing on a Toronto bus.

The incident took place around 11:45 p.m. on a TTC bus near Keele Street and Donald Avenue, near Eglinton Avenue.

Toronto paramedics say an adult was transported to a local hospital for treatment.

Police say the suspect and victim were known to each other; however no suspect descriptions have been provided at this time.

The stabbing comes two days after a teenager was killed in a violent, “unprovoked,” incident at the Keele TTC station.

Police say a 16-year-old male was sitting on a bench in the station’s lower level when a suspect approached and stabbed him.

The victim, who police have identified as Toronto resident Gabriel Magalhaes, was rushed to hospital with life-threatening injuries. He later died.

A 22-year-old man has been charged with first-degree murder in connection with the incident.

In a statement, Toronto’s Deputy Mayor Jennifer McKelvie called the teen’s murder a “tragedy.”

“My thoughts are with Gabriel Magalhaes' family and friends as they mourn this loss,” she said
