Two shopkeepers were left “terrified” by a stand-off with two armed raiders who burst into a Blackpool store and demanded money, police said.
One of the would-be robbers threatened the brothers with a six-inch carving knife at the Selbourne Mini Market, on Caunce Street, on Thursday evening.
One of the victims, both Sri Lankan, picked up a chair to keep the thugs – a man and a woman – at bay until they ran off empty handed after being spooked by a customer walking into the store.
Two people were last night in custody for the offence, which took place at around 11pm.
Det Sgt Mark Dickinson, of Blackpool CID, said: “The man has brandished a kitchen-style carving knife with a six-inch blade and demanded money.
“The victims have told us they were terrified and the ordeal has left them badly shaken up.”
The offenders are believed to have fled the scene after being disturbed before ditching clothing in a nearby bin, at the junction of Caunce Street and Selbourne Road. The items were recovered by police although the knife has yet to be found.
Det Sgt Dickinson added: “One of the shopkeepers has armed himself with a chair to protect himself and his brother, the other shopkeeper.
“There has been a stand-off with the offenders, who left when another customer entered the shop. They made off empty handed.”
Police arrested a 24-year-old woman and a 28-year-old man, both from Blackpool, on suspicion of attempted robbery following the offence.
Anyone who with information should call police on 101.
