SIU Investigating After Police Officer Discharges ARWEN at Man in Windsor

Case Number: 22-OFP-307   

Mississauga, ON (2 December, 2022) ---
The province’s Special Investigations Unit is investigating after a Windsor Police Service officer discharged an Anti-Riot Weapon Enfield (ARWEN) yesterday at a 42-year-old man.

Preliminary information suggests the following:
  • At approximately 2:45 p.m. on December 1, 2022, Windsor Police Service officers responded to a home in the area of Lauzon Parkway and McHugh Street for a person in distress call.
  • After a period of negotiations, the man opened the front door of the residence.
  • There was an interaction, and one office deployed his ARWEN at the man.
  • The man was struck and subsequently apprehended. He did not sustain any serious injury.

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

Although the man did not sustain any serious injury, 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:
