Chief cops a nasty shock.
Chief Constable Richard Brunstrom shouted, "Bloody hell" as he was subjected to a 1.5 second, 50,000 volt shock.
Brunstrom, an officer with North Wales police, had agreed to be a guinea pig for the device which is intended to pacify offenders without the need for lethal force.
The test firing is shown on the force's website.
Brunstrom said: "We're prepared to use this on members of the public when we have to. It's right and proper that the head of the organisation tries it out for himself."
