Mississauga, ON (10 August, 2022) ---
The province’s Special Investigations Unit is investigating after a York Regional Police Service (YRPS) officer discharged an Anti-Riot Weapon Enfield (ARWEN) today at a 26-year-old man. 

Preliminary information suggests the following:
  • At approximately 6 a.m. on August 10, 2022, YRPS officers were dispatched to a home on Cashel Court in relation to an intruder call. Officers were given information that the person of interest had a knife.
  • Once at the scene, officers contained the area.
  • At approximately 8 a.m., one officer discharged his ARWEN at the man. Two officers deployed their conducted energy weapons (CEW) at the man.
  • The man was apprehended and transported to hospital. 

At this time, it does not appear that the man suffered any serious injury as a result of the ARWEN deployment.

One investigator and two 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.
