A 19-year-old woman is being treated for serious injuries after being ejected from a vehicle that went into a ravine in Richmond Hill on Wednesday morning.

According to York Regional Police spokesman Const. Blair McQuillan, an officer was doing radar enforcement when he observed the vehicle travelling at a high rate of speed and attempted to pull it over.

The vehicle veered off the road and went down an embankment on the east side of Bathurst Street, just south of Rutherford Road, at about 7:30 a.m.

The car came to a stop at a small stream.

Firefighters rescued the female driver, who was thrown from the vehicle.

The Special Investigations Unit is investigating the incident.

According to the SIU, the woman's injuries include fractures to her arm and leg. She was taken to Sunnybrook hospital in Toronto.

The SIU investigates reports involving police where there has been death, serious injury or allegations of sexual assault.
