MASKED raiders armed with a sledgehammer and a concrete slab fled empty handed after a bungled robbery at a Post Office in Prestwich.

Two men entered the branch in Whittaker Lane at 9.30am yesterday, and escaped after failing to smash the security screen.

The getaway car, a stolen white Ford Mustang driven by a third masked man, was later found abandoned in Green Walk, Prestwich. Staff were left shocked but unhurt.
