If you're going to try to rob a jewellers, maybe don't pick one owned by a man who's a black belt in martial arts.
The 71-year-old jewellery store owner got a shock when the would-be robber attempted a heist on his store.
The thief-to-be entered Coopers Jewellery store in Barnstaple, North Devon and began wielding a gun at the shopkeeper and even fired a shot at him, reports the Huffington Post.
CCTV footage has since emerged of the incident, showing owner David Bruce teaching the imposter - who was wearing a latex mask, sunglasses and a black coat - a fine lesson in martial arts.
Mr Bruce, who was alone when the intruder entered the shop, threw some moves and then grabbed a baseball bat and successfully won the tense confrontation.
The black-belted business owner used his wisdom of self-defence to fight off the masked trespasser as he waved the gun in his direction.
He hit him with the bat on the wrist and chased him from the shop - but only after the man had fired off a shot, luckily missing him.
Mr Bruce told The Mirror: "He was quite scary looking, but I don't mind it as I like a fight. I come from the school of hard knocks, if you know what I mean, and don't take kindly to having a gun waved around in my face."
Devon and Cornwall police have since released a statement and are asking for the public to review the footage in an attempt to identify the offender.
Detective Inspector Praveen Naidoo said: "We are particularly keen to speak to anyone who may have seen the man entering or leaving the town centre area or anyone with information as to his identity.
"He most likely left the scene with injuries to his right hand and head."
