The province’s police watchdog is investigating after a police officer was shot when a fellow officer opened fire at a man during a mental health call in Oshawa.

The shooting happened near Simcoe Street and Wentworth Street E, Durham Regional Police Service said in a social media post. Police said they were called to the scene for a report of an armed person.

There, they found a 27-year-old man armed with a knife, the SIU said. The man did not appear to have a firearm.

An interaction ensued and one officer discharged their firearm multiple times, striking the man and another police officer, the SIU said.
