We are appealing for information following a robbery at Booths supermarket in Sharoe Green Lane, Fulwood.
At 9.50pm on Saturday November 25, four men wearing dark clothes and balaclavas entered the shop armed with knives and a baseball bat.
They approached the cigarette kiosk and threatened staff before jumping over the counter and stealing cigarettes and cash from the till.
Two of the men tried to access the safe before they fled the scene in a dark coloured vehicle.
Det Insp Roger Ashcroft, of Lancashire Constabulary, said: “This was a frightening incident for staff and members of the public who were in the store at the time.
“While robberies of this type are rare, we would urge shoppers and businesses to remain vigilant and report any suspicious activity around shops and cash machines.”
Anyone with information is asked to call 101 quoting log ref LC-20171125-1429.
