Denman Fatburger Crash Injures Officers In Vancouver

Vancouver police officers have been injured after a car crashed through the front of a Fatburger restaurant in the West End on Sunday night.

From The Canadian Press:

VANCOUVER - Vancouver police say speed and alcohol do not appear to be factors, but investigators still aren't sure why a small car slammed into a West End restaurant, injuring four officers dining inside.

The crash occurred at around 8 p.m. Sunday night and the scene remain taped off, with the car still embedded in the building 12 hours later.

Police spokesman Const. Brian Montague says the four injured officers were released from hospital overnight.

The members, who have between one and nine years of service, are recovering at home from injuries that include broken bones.

The 30-year-old woman who was driving the car was not hurt, but why her BMW veered into the burger restaurant (in the 1100 block of Denman Street) is still being probed.

Officers with the Collision Investigation Unit want to know if the driver might have had a medical condition or been distracted by using a cellphone
