This is the dramatic moment a screwdriver-wielding thug tried to rob a newsagents - before being fought off by its elderly owners. Shocking CCTV footage shows the man bursting into Pitville Convenience Store and demanding that shop owner Dolly Karim, 75, hand over the till. Incredibly, the brave gran-of-eight refuses, instead picking up a wooden stick stashed behind the counter and whacking him with it. The yob, in his 30s, then drags the till unit off the counter and makes a dash for the door of the newsagents in Cheltenham, Glos., with it in his arms.
