SIU Concludes Investigation into Woman’s Broken Knee in Innisfil Arrest
Case Number: 25-OCI-343
The Director of the Special Investigations Unit, Joseph Martino, found no reasonable grounds to believe a South Simcoe Police Service (SSPS) officer committed a criminal offence in connection with the fractured left knee suffered by a 40-year-old woman in 2023. The SIU began investigating on September 4, 2025, after the SSPS notified the SIU that they were in possession of information that the woman was seriously injured during her arrest on March 10, 2023.
The night of March 10, 2023, SSPS officers were called to a residence in Innisfil after the woman’s boyfriend reportedly assaulted her. She was eventually arrested for trespassing when she did not move quickly enough to vacate the home, owned by her boyfriend’s family. The woman fell during the arrest process, fracturing her left knee.
Full Director’s Report (with Incident Narrative, Evidence, and Analysis & Director’s Decision):
The SIU is an independent government agency that investigates the conduct of officials (municipal, regional and provincial police officers, police officers with the Nishnawbe Aski Police Service, 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
