SIU Lays Assault Causing Bodily Harm Charge Against Sarnia Police Officer

Case Number: 22-OCI-317   

Mississauga, ON (6 July, 2023) ---
The Director of the Special Investigations Unit, Joseph Martino, has reasonable grounds to believe an officer with the Sarnia Police Service committed a criminal offence in connection with a serious injury suffered by a 35-year-old man. On October 23, 2022, officers responded to St. Paul’s Church on Devine Street for a reported trespass investigation. The man was arrested and subsequently diagnosed with a serious injury.

As a result of the SIU investigation, Cst Sean Van Vlymen is charged with one count of assault causing bodily harm contrary to section 267(b) of the Criminal Code.

Cst Van Vlymen is required to appear before the Ontario Court of Justice at 700 Christina St. N., on August 3, 2023.

As the matter is before the courts, and in consideration of the fair trial interests of the accused, the SIU will not provide further comment on the investigation.

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
