Police said Shane Reely, 23, was a passenger in the stolen vehicle. He has been charged with possession of stolen property over $5,000 and breach of a recognizance.

Both remain in custody until their next court appearance. Hutchinson is scheduled to appear in court on Wednesday and Reely is scheduled to appear on Thursday.

Ottawa police said more charges could be laid.

Driver refused to go to hospital

An RCMP vehicle and a car collided in front of the Supreme Court of Canada after a short police pursuit Sunday. RCMP tried to pull over what was believed to be stolen car on the Sir John A. MacDonald Parkway on Sunday afternoon when the car sped away, RCMP said.

RCMP said it notified Ottawa police that the car was headed into its jurisdiction but did not pursue the car. Ottawa police said before locating the car, it received a call about a crash in front of the Supreme Court of Canada on Wellington Street around 3:30 p.m. It involved a different RCMP vehicle than the one on the Sir John A. MacDonald Parkway.

Six people were inside the car, including the critically-injured woman. Four other passengers suffered minor injuries, police said.

A 47-year-old male RCMP officer also suffered minor injuries.

The driver of the vehicle was assessed on scene but refused to go to hospital, police said.

Ontario's Special Investigations Unit was not involved in the investigation, as they only get involved in incidents involving police forces under provincial jurisdiction, which does not include the RCMP.
