MISSISSAUGA, Ont. - Ontario's police watchdog has charged an officer with assault after a man was injured during the course of an arrest.

The Special Investigations Unit says the officer was dispatched to arrest a man in Parry Sound, Ont., in June.

The unit says that while the officer was arresting the man, there was an "interaction" and the man was injured, and required treatment.

The SIU says the officer has been charged with assault causing bodily harm.

He's scheduled to appear in court next month.

The Special Investigations Unit is an arms-length agency that's automatically called in to investigate reports of death, serious injury or sexual assault involving police.
