There’s been a lot of this about in Essex recently - the Morrison's close to me was one victim, and, apparently, a shop on Mersea Island too, as well as other places. I’m not sure if it was the same people in each case, but the methods used seem very similar in each case (if what you read in papers/on the internet is accurate).
