Two men agreed to buy electronic products from a man outside a pub, but received a backpack of bricks for their £1,000 in cash.
At around 4.15pm on November 4, the two men were outside the Walkabout pub on the High Street, when another man offered to sell them electronics.
He said he was selling two top of the range laptops and three iPhones for £1,050. The men agreed to buy them and withdrew the cash from Lloyds TSB in High Street.
The offender took them to his car, a dark coloured Vauxhall, which was parked in St Rumold Street and showed them the laptops and phones.
They got out of the car and the offender also got out and handed them a rucksack in exchange for the cash.
When the offender had left the scene, the two men opened the bag and saw it was full of bricks.
Police are calling on the public to help them identify and arrest this scammer, and warning people to only ever buy goods from reputable sources.
Police say the man (pictured) is not thought to be from the area and may well be travelling around the region using this scam.
