Police are appealing for witnesses following a robbery at the Co-Operative store in Kilbarchan.
Around 8.35pm a man entered the Co-Operative store on High Barholm and threatened members of staff with a weapon.
He then left the premises with a three-figure sum of money and headed towards the Johnstone area.
No members of staff were injured.
The suspect is described as white, in his 30s, 5ft 8 to 5ft 9, of medium build and spoke with a distinctive accent, possibly English. He was wearing a dark coloured hooded top with the hood up and dark trousers. He was also carrying a white carrier bag.
Detective Constable Grant Spy said: “We are carrying out enquiries in the local area including checking CCTV in an effort to trace the man responsible and police patrols in the area have been increased as a result.
“The weather at the time of the incident was particularly bad and anyone out walking at the time would have stood out due to this.
“Paisley CID can be contacted on the non-emergency number 101 or alternatively you can call CRIMESTOPPERS on 0800 555 111, where anonymity will be maintained.”
