Detectives are hunting three robbers after two raids at Sainsbury’s stores in Sheffield in less than 48 hours.
A knife-wielding raider burst into the Sainsbury’s store on Gleadless Road, Gleadless at about 6.30am on Tuesday.
The masked man threatened staff with a knife before fleeing the scene with a quantity of money.
Police said no-one was injured in the terrifying robbery.
The man is described as white, 5ft 7ins, stocky build and wearing a dark, hooded top with a balaclava.
Police say he was wearing tracksuit bottoms and dark coloured trainers.
Less than 48 hours later, a second Sainsbury’s store, on Bradway Road, Bradway, was targeted by masked raiders.
Two white men wearing hooded tops and ski masks entered the store at about 9.50pm on Wednesday.
The masked duo demanded money from staff and fled the store with a quantity of cash.
Police do not believe anyone in the store at the time was threatened or the men used weapons during the robbery.
Detectives do not believe the two incidents are connected to others across Sheffield.
A force spokesman said: “At this time, police do not believe that this incident is linked to other reported robberies in the city.”
The robberies come just weeks after the Bradway store was last targeted by raiders.
Two robbers entered the store at about 9pm on Thursday, January 8.
They escaped with money after demanding cash from two members of staff.
The men, both dressed in dark clothing, fled on foot along a footpath which leads to the back of the store and on to open land.
