Liam Meighan, 23, allegedly tried to steal Buckfast and cigarettes using a concealed stick that he claimed was a gun.

But on moving to leave the store, he was tackled to the ground by the fourth dan black belt martial arts expert that had served him.

The shopkeeper then restrained him until the cops arrived.

James Irvine, defending, told Kilmarnock Sheriff Court: “You have seen the video. It is clear that summary justice was meted out very quickly.”

Sheriff David Hall deferred sentence until 29 November.
