One man has suffered non-life-threatening gunshot wounds and a second man is injured after an attempted arrest in Langley.
The Independent Investigations Office investigates all matters of officer-related injury or death and confirms it has been called.
A statement from Delta police says its officers had tracked the men to Langley as part of a Delta-related case and the injuries occurred last night as the arrest was underway, but it doesn't say how the second man was hurt.
The IIO is appealing for any witnesses to the arrest while Delta police say the criminal case against the men has been taken over by RCMP while the probe of the shooting is underway.
