STAFF at Maplins and Staples at Greenbridge Retail park were alerted to the use of fake £50 notes when several punters attempted to use them to pay for goods earlier this year.
The CCTV images are the latest to be shared with the Adver in a bid to net criminal for unsolved offences.
Three men entered each of the stores on Jaunary 22 at around 3.48pm and attempted to pay for goods with the counterfeit money.
The suspects are decribed as white men. The first was of stocky build, with short dark hair, wearing a grey hoodie with the hood pulled up, black tracksuit bottoms with blue lines down the side and blue and white trainers.
The second man had short dark hair, was wearing a black coat, blue jeans and black trainers and the third man was wearing a dark jacket.
Anyone with any information should contact the Swindon Crime Management Unit on 101 quoting crime reference number 54140007256.
