Mississauga, ON (30 August, 2022) ---
The province’s Special Investigations Unit is investigating after a Thunder Bay Police Service (TBPS) officer discharged an Anti-Riot Weapon Enfield (ARWEN) yesterday at a 24-year-old man.

Preliminary information suggests the following:
  • On the evening of August 29, 2022, TBPS officers had information that an individual of interest was in a residence on Ambrose Street.
  • Officers were dispatched to the residence and communication was made with the occupants of the home.
  • When a man came out of the home, there was an interaction between him and police. An ARWEN was deployed and the man was struck. The man was also bitten by a police dog. He was taken to hospital for treatment.

Three investigators and two forensic investigators 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: https://siu.on.ca/en/appeals.php



The SIU is an independent government agency that investigates the conduct of officials (police officers as well as special constables with the Niagara Parks Commission and peace officers with the Legislative Protective Service) that may have resulted in death, serious injury, sexual assault and/or the discharge of a firearm at a person. All investigations are conducted by SIU investigators who are civilians. Under the Special Investigations Unit Act, the Director of the SIU must

  • consider whether the official has committed a criminal offence in connection with the incident under investigation
  • depending on the evidence, cause a criminal charge to be laid against the official where grounds exist for doing so, or close the file without any charges being laid
  • publicly report the results of its investigations
