VICTORIA -- No charges will be laid against a Mountie in Langley, B.C., who told a civilian to stop trying to resuscitate a dying man.

The civilian complained to the RCMP and the Independent Investigations Office determined that the officer might have committed an offence.

The B.C. Crown prosecutor's office says it happened last September when a man crashed his vehicle because of a medical event and a person on the scene started CPR.

The office says when the RCMP officer arrived, he checked the driver's pulse and, because he thought the man was breathing, he ordered the person to stop CPR.

Firefighters arrived and could not find a pulse and so started CPR again; despite numerous medical interventions, the man died in hospital.

The prosecutor's office says charges will not be laid because there's no substantial likelihood that the officer involved would be convicted.
