Armed robbers threatened staff at a foodstore with an axe before making off with a substantial amount of cash, police have said.
Two men entered the Midlands Co-operative foodstore in Stamford, Kettering, and threatened staff with the hand axe before making off in the direction of Grange Road.
The men were wearing balaclavas, dark jeans and hooded tops with the hoods up.
Police are appealing for anyone with information on the incident, which happened on Wednesday around 7pm, to contact them.
DC Billy Roberts, of Northamptonshire Police, said: "Thankfully nobody was hurt during the incident, though the staff were understandably very upset by what took place.
"I would like to reassure the local community that this is a very rare offence and we are working hard to establish who was responsible for it and to bring those offenders to justice.
"I would particularly like to hear from anybody saw two men acting suspiciously in the vicinity of the foodstore on Stamford Road on the day before the offence took place."
