MISSISSAUGA, Ont. -- The Special Investigations Unit says two Durham regional police officers are facing multiple charges arising from the arrest of a 35-year-old man in April last year.

The police watchdog agency says the man was a passenger in a vehicle pulled over in Oshawa, Ont., on the night of April 26, 2017.

The SIU says the man became involved in an interaction with the officers, was arrested and taken to the police station.

Shortly after, the man was taken by ambulance to hospital where he was diagnosed with a serious injury.

The SIU says Const. James Edward Scholts, 42, and Const. Thomas Broadfoot, 35, are charged with assault causing bodily harm, obstruction of justice, and obstructing a peace officer. They are to appear in Oshawa court on March 22.

The SIU is an arm's-length agency that investigates reports involving police where there has been death, serious injury or allegations of sexual assault.
