Police are appealing for witnesses and video footage following an armed robbery at a convenience store in Middlewich.
At around 11.05am on Sunday 3 July an unknown man wearing a face covering entered the Morrisons Local store on Poplar Drive.
The offender threatened members of staff with a knife and demanded they handed over money from the tills.
The man then fled the store with a quantity of cash and got into a blue car which was parked outside; the vehicle was seen to drive off in the direction of Long Lane South.
A 23-year-old local man has since been arrested on suspicion of robbery in connection with the incident; he is currently being questioned by officers.
Enquiries in relation to the incident are ongoing and detectives are urging anyone with any information to come forward.
Detective Sergeant Kate Palin, from Kate Palin CID, said:“Thankfully on this occasion there were no reports of any injuries, although the staff were left shaken as a result of their ordeal.
“While a man has been arrested in connection with the robbery, our enquiries remain ongoing.
“As part of the investigation I am keen to hear from anyone who was in the area between 10.45am and 11.45am on Sunday 3 July and thinks they have witnessed the incident or seen the offender before or after the robbery.
“The same goes for anyone who thinks they may have CCTV or dashcam footage which may aid our investigation.”
