EXCLUSIVE: Chorlton Tesco Metro Armed Hold Up

Last night, about 11 pm or so two masked men, armed hold up, at cashpoint outside, place swarming with bobbies. Tesco Metros have just discontinued previous private Security contract ... This new store was also robbed in March. Looks to me like the place is probably doing £30,000 plus a week turnover, plus fuel. Why false economy on security?
