The Special Investigations Unit has terminated its investigation into a gunman’s 12-hour standoff with York Region police in Richmond Hill, saying it doesn’t have jurisdiction because the suspect wasn’t seriously hurt.

The standoff began at around 10:30 a.m. Dec. 27 when a York Region police officer attempted to arrest a man at a gas station at Bayview Avenue and Major Mackenzie Drive for allegedly breaching his bail conditions.

The man ran and allegedly exchanged gunfire with the officer before getting into his vehicle and driving home, barricading himself inside, the SIU said in a news release Monday.

At around 9:40 p.m., police threw tear gas into the home and the man allegedly used a long gun to shoot at officers, the SIU said.

The man surrendered at around 10:30 p.m.

The SIU is an arm’s-length provincial agency tasked with investigating incidents involving police officers that lead to serious injury or death as well as sexual assault allegations against officers.

The agency invoked its mandate at the time as it was unknown whether the suspect had been shot, but discontinued its investigation after finding out that the man was not seriously injured.

“Based upon the SIU’s preliminary inquiries, including an interview with the man and a review of a video recording of the incident from the gas station, it is evident that the man did not sustain any serious injury. Consequently, the SIU is without statutory jurisdiction to proceed further with its involvement in the matter. The SIU investigation is therefore discontinued and the file is closed,” SIU director Joseph Martino said in the news release.

Anoshirvan Shirizadeh, 34, faces 13 charges, including attempted murder, careless use of a firearm and pointing a firearm.
