A B.C. RCMP officer is facing possible impaired driving charges after she was stopped on suspicion of drunk driving after leaving the Cascades Casino in Langley.

Langley RCMP said they received a complaint July 2 about a suspected drunk driver leaving the casino. They located the vehicle and driver, who turned out to be an off-duty officer assigned to the E division headquarters in Vancouver.

The investigation is continuing and no charges have been laid, according to a statement released by RCMP Cpl. Annie Linteau on Wednesday morning.

The officer's status will be reviewed after the Crown decides whether to lay charges, the statement said. She will not be named publicly unless she's charged.

"Every police officer has seen first-hand the trauma and heartbreak caused by drinking and driving," Linteau said. "Every case of impaired driving is disappointing but especially when it involves a police officer."
