The province's police watchdog is investigating after a collision in Oshawa sent four people to hospital over the weekend.

An Ontario Provincial Police officer was patrolling Highway 401 near Thickson Road in Whitby on Sunday at about 3:30 p.m. for speed limit enforcement, according to preliminary information via email from the Special Investigations Unit (SIU) Sunday night.

The officer attempted to stop a driver in the east lane, who allegedly fled, according to the statement.

The driver was involved in a single vehicle rollover "a short time later" near Stevenson Road in Oshawa, the SIU said.

The agency said all four occupants of the vehicle have been taken to hospital with serious but non-life-threatening injuries.

The collision and investigation shut down right on and off ramp lanes on the Highway 401 at Stevenson Road in Oshawa Sunday evening.

The SIU investigates the conduct of police officers in incidents that may have resulted in death, serious injury, sexual assault or the discharge of a firearm at someone.
