A convenience store was burgled twice in three days, with an employee saying he felt sure it had been targeted by professionals. Shift manager at the shop in Swindon, Wiltshire, Nathan Humphries, said: "They came through the back door and must have used a crowbar to prise open the shutter. I'm sure they were professionals." He added: "We were worried about our payroll information but we've been told they shouldn't be able to access it."
