SIU Concludes Investigation into ARWEN Deployment at Man in Sabaskong First Nation

Mississauga, ON (9 June, 2025) ---
The province’s Special Investigations Unit is investigating the circumstances surrounding the deployment of an Anti-Riot Weapon EnField (ARWEN) at a 22-year-old man yesterday in Onigaming First Nation.

Preliminary information suggests the following:
  • On the morning of June 8, 2025, Emergency Medical Services (EMS) attended a home on the reserve to render assistance to an individual. Following a confrontation with the individual, EMS retreated and contacted police for assistance.
  • Ontario Provincial Police officers from the Emergency Response Team and Canine Unit, as well as Treaty Three Police Service officers, were dispatched to the residence and the scene was contained.
  • Upon the man exiting the residence, there was an interaction between him and officers. One OPP officer deployed his ARWEN at the man, and the man was struck. 
  • The man was subsequently arrested. He did not suffer any serious injury.

Two investigators and one forensic investigator have been assigned to the case. 

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: https://siu.on.ca/en/appeals.php
