Ontario’s police watchdog is appealing for witnesses after a 16-year-old girl was taken to hospital following an incident involving Sarnia police Thursday.

Sarnia police officers were dispatched for a disturbance call at the corner of Capel and Exmouth streets just after 6 p.m.

Once at the scene, an officer was involved in an “interaction” with a 16-year-old girl, according to a release from the Special Investigations Unit.

The teen was taken to Bluewater Health where she was treated for an upper body injury and later released, according to the SIU.

Three SIU officers have been assigned to investigate the circumstances around the incident.

The SIU is called in to investigate reports involving police where there has been death, serious injury or allegations of sexual assault.

If anyone has any information on Thursday’s incident, the SIU asks them to speak to the lead investigator by calling 1-800-787-8529.
