SIU Investigating Discharge of ARWEN at Man in Uxbridge

Case Number: 23-OFP-076   

Mississauga, ON (10 March, 2023) ---
The province’s Special Investigations Unit is investigating after a Durham Regional Police Service (DRPS) officer discharged an Anti-Riot Weapon Enfield (ARWEN) yesterday at a 40-year-old man.

Preliminary information suggests the following:
  • Shortly before 6:30 p.m. on March 9, 2023, DRPS received a call regarding a dispute between family members at a home in the area of Balsam Street and Brock Street West.
  • Shortly after officers arrived at the residence, there was an interaction between officers and the man. One officer discharged his ARWEN and the man was struck. Two other officers deployed their conducted energy weapons.
  • The man was transported to hospital for treatment of a serious injury.
Three investigators and one forensic investigator have been assigned to the case. 

An ARWEN is classified as a firearm. Under the Special Investigations Unit Act, a firearm is defined as a barreled weapon from which any shot, bullet or other projectile can be discharged and that is capable of causing serious bodily injury or death to a person.

The SIU is urging anyone who may have information about this investigation, including video or photos, to contact the lead investigator at 1-800-787-8529 or online at:
