A 33-year-old man has died after police responded to a call for an armed robbery at Warden subway station.

The Special Investigations Unit, Ontario's arms-length police watchdog, is probing the circumstances of the shooting.

In a news release, the SIU said a 911 call was placed around 12:16 a.m. When officers from the Toronto Police Service arrived, there was an interaction between them and a man which resulted in the man being fatally shot.

CP24 has learned that a bystander at Warden station called 911 to report that a man armed with a gun was robbing a TTC collector. The collector, who is reported to be okay, handed over some money.

When police responded, they had a description of the suspect and tracked him a short distance away at 682 Warden Ave., a Toronto Community Housing Corporation building. Residents there told CP24 that the suspect lived on the second floor of the building.

An altercation took place outside the building and the suspect was pronounced dead at the scene.

Eight SIU investigators and 3 forensic investigators have been assigned to the case. The SIU is called in whenever there are reports of serious civilian injuries, deaths or sexual assault involving police.

Warden subway station remains closed while police investigate. Shuttle buses are operating from Victoria Park to Kennedy stations. All buses servicing the station are also diverting.
