SIU Investigating After Police Officer Discharges ARWEN at Man in Ottawa

Case Number: 22-OFP-172   

Mississauga, ON (5 July, 2022) ---
The province’s Special Investigations Unit is investigating after an Ottawa Police Service officer discharged an Anti-Riot Weapon Enfield (ARWEN) yesterday at a 37-year-old man. 

Preliminary information suggests the following:
  • At approximately 12:30 p.m. on July 4, 2022, Ottawa Police Service officers were dispatched to a residence on Claremont Drive in relation to a man breaching his conditions.
  • The man refused to exit the residence, threatening to harm himself if the officers came in. Negotiations continued.
  • Some time later, officers observed the man with a self-inflicted wound to his neck. There was an interaction, and one officer discharged his ARWEN. The man was taken into custody and transported to the hospital. At this time, it does not appear that the man suffered any serious injury as a result of the ARWEN deployment.
Three investigators and one forensic investigator have been assigned to the case.  

The SIU’s mandate was invoked because a police officer discharged an ARWEN, which 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:
