'Shocking' armed Slough Co-op store raid
Police are hunting two men who threatened staff during a "shocking" armed robbery at a shop in Slough.
The pair, described as white and in their 20s, brandished what was thought to be a handgun and chisel as they raided the Co-op in Kennedy Parade.
They smashed the till with the chisel and stole cash, before fleeing the scene on bicycles, on Friday night.
Police said one offender may have been hit by a vehicle near to Long Furlong Drive and Wentworth Avenue.
An off-duty police officer who saw the men leaving the store gave chase "for some time" before losing sight of them, the force said.
Det Sgt Peter Wall said: "This was shocking for the staff members who were threatened with what at first appeared to be a gun but may have been an imitation firearm.
"It was fortunate no innocent member of the public was hurt during this incident."
