BURNABY, B.C. - British Columbia's police watchdog is investigating a shooting involving the Burnaby RCMP that sent one man to hospital.

RCMP say officers driving on patrol at about 2:45 a.m. Sunday saw what appeared to be a robbery underway in a 7-Eleven near Canada Way and Edmonds Street.

Mounties say the officers engaged with the suspects and attempted to make an arrest, but the men entered a van and a police car was rammed.

Shots were fired and both suspects fled in the van until it crashed near the intersection of Canada Way and Rosewood Street.

One man is believed to have sustained a gunshot wound and is in hospital with non-life-threatening injuries, while another man was taken into custody without incident.

The IIO investigates in police-related incidents involving death or serious harm, and the office has sent a team of investigators to the 7-Eleven and the collision site.
