North Wales Police are urging businesses to be vigilant after reports of fake £50 being used the region.
It comes after several incidents of passing counterfeit notes have occurred in the Gwynedd south area over the last 24 hours.
The two men and a woman are travelling in a dark blue Ford Transit, and have Irish accents. One of the men has what is described as having an “Angel wing” tattoo on the left side of his neck.
The individuals concerned have mostly attempted to pay for low value goods using fake Bank of Ireland £50 notes in Penrhyndeudraeth, Blaenau Ffestiniog and Porthmadog.
Although there has been no formal warning about such notes being used elsewhere, police say that they believe the “individuals may travel throughout the North Wales area”.
A police spokesperson added: “As such we advise anyone who is offered a Bank of Ireland £50 note to undertake the usual checks, and if any suspicious circumstances occur, please contact us on 101 or via the live webchat.
“Likewise, any sightings of the distinctive vehicle pictured which has Irish number plates should be reported immediately.”
