In an incident that has caught the attention of the Pembroke community, the Ontario Special Investigations Unit (SIU) has invoked its mandate following a police arrest that resulted in a 44-year-old man experiencing medical distress. The situation unfolded on December 2, 2025, when officers from the Upper Ottawa Valley Detachment of the Ontario Provincial Police (OPP) responded to a disturbance at a residence on Pembroke Street West.

Upon arrival, the OPP arrested the man, who was wanted on an outstanding warrant. The police also seized two loaded firearms and a quantity of suspected cocaine from the scene. While the arrest proceeded without incident, the situation took a serious turn when the man began to show signs of medical distress while being transported in the back of a police cruiser.

Emergency services were called, and he was promptly taken to the hospital for treatment. Following this incident, the OPP notified the SIU, a civilian agency responsible for investigating incidents involving police that result in serious injury or death. The SIU officially invoked its mandate on December 3, indicating that they will now handle the investigation into the circumstances surrounding the man’s medical emergency.

The decision to involve the SIU underscores the agency’s commitment to transparency and accountability in policing, especially in cases where individuals may experience health crises while in custody. In such situations, the SIU conducts thorough investigations to determine whether the actions of police contributed to the medical distress.

As this investigation is underway, the OPP has stated that they will not provide further information regarding the case, emphasizing the importance of allowing the SIU to conduct its work without interference.

The Pembroke community, known for its close-knit atmosphere and strong support for local law enforcement, will be closely observing the developments as the SIU works to provide answers. Incidents like this can raise questions about police practices and the health and safety of individuals in custody, and it will be important for the community to stay informed as the investigation unfolds.

For now, residents are reminded of the importance of understanding their rights and the protocols in place for ensuring accountability within the police system. The SIU’s involvement serves as a reminder that oversight mechanisms are in place to address concerns about police conduct, and that the health and safety of all individuals—whether under arrest or otherwise—is a priority.

As the investigation progresses, it is hoped that clarity will be brought to this concerning situation, reinforcing the community’s trust in law enforcement while ensuring that all proper protocols are followed in the treatment of individuals in custody.
