CHILLIWACK, B.C. -- British Columbia's police watchdog is investigating the death of a man who was hit with a stun gun in Chilliwack.

The Independent Investigation Office says RCMP officers were responding to a reported parental abduction on Saturday afternoon.

It says before officers arrived, the man was "confronted by a member of the public" who tried to restrain him.

The IIO says RCMP report that a stun gun was deployed during an "interaction" with the man, and he went into "medical distress."

The agency says emergency medical services were called, but the man did not survive.

Investigators have been at the scene obtaining evidence, reviewing available surveillance camera footage, and interviewing both civilian witnesses and police officers.

The IIO investigates all incidents involving police officers that result in serious injury or death.
