Police are investigating an armed robbery at the Co-Operative in Kilbarchan on Sunday night.
The incident occurred around 10pm on Sunday, November 9, at the shop in High Barholm.
A man threatened two shop assistants with what appeared to be a firearm and demanded money from them.
The suspect then left the shop with a four figure sum of cash and was last seen heading towards a nearby cycle path.
The firearm was not discharged at any time.
The female shop assistant aged 22 and male assistant aged 23 were not injured during the incident but were left extremely distressed as a result.
The suspect is described as white, 20-25 years, 5ft 10, thin build and was wearing dark clothing including a dark hat and scarf.
Detective Inspector Sandy Nelson at Paisley CID said: “This was a very traumatic experience for the young shop assistants which luckily did not result in any injuries.
“I’d like to speak to anyone who may have seen the suspect hanging about the area prior to the robbery taking place or anyone who saw him leaving the shop afterwards.
“Our enquiries have revealed that there was a small red car near to the shop at the time of this robbery and I’m keen to speak to the driver or any passengers as they may have information that could assist our enquiries. In addition I’d also like to speak to anyone who observed this car in the vicinity around 2200 hrs last night.”
Anyone with information is asked to contact Paisley CID on telephone number 101 or alternatively CRIMESTOPPERS on 0800 555 111 where anonymity can be maintained.
