SIU Lays Assault Charge Against Police Officer in Relation to Incident in Waterloo Detention Unit

Case Number: 20-OCI-049

Mississauga, ON (14 June, 2020) ---
The Director of the Special Investigations Unit (SIU), Joseph Martino, has reasonable grounds to believe a Waterloo Regional Police Service (WRPS) officer committed a criminal offence in relation to an interaction with a 44-year-old man in March of 2020. As a result, Director Martino has caused a charge to be laid against the officer.  

The SIU investigation determined that on March 5, 2020, the man was arrested in the area of King Street East in Kitchener and transported to the WRPS Central Division Detention Unit. In the booking hall, the man became involved in an interaction with a police officer. The man was transported to hospital where he was diagnosed with serious injuries.

As a result of the SIU investigation, WRPS Sergeant Paul Tranter has been charged with one count of assault causing bodily harm, contrary to s. 267(b) of the Criminal Code

The officer is required to appear before the Ontario Court of Justice at 85 Frederick Street in Kitchener on July 8, 2020. 

The matter is now properly before the courts. In consideration of the fair trial interests of the accused, the SIU will make no further comment pertaining to this investigation.  


The SIU is an arm’s length agency that investigates reports involving police where there has been death, serious injury or allegations of sexual assault. Under the Police Services Act, the Director of the SIU must

  • consider whether an officer has committed a criminal offence  in connection with the incident under investigation
  • depending on the evidence, lay a criminal charge against the officer if appropriate or close the file without any charges being laid
  • report the results of any investigations to the Attorney General.
