In an interview with the BBC, he recounted how he frantically scanned the shelves for some sort of tool that'd help him bust out, and settled on a hefty 1.5-foot frozen log of black pudding (a type of blood sausage).
"It was the right shape. I used it like the police use battering rams to break door locks in. It was solid, pointed and I could get plenty of weight behind it," he said. "I'm lucky really. We sell about two or three each week and that was the last one in there."
