Gardaí are warning businesses in north county Dublin to be vigilant after credit card fraud in the area.
Officers are appealing to retailers to make their staff aware of potential fraudulent behaviour.
They say there have been five incidents in Balbriggan in recent days.
They involve customers using cards with either just card details and no card present, or a card has been present but has passed its expiry date. In some cases the cards were used to get cashback.
As the busy shopping period approaches Gardaí are advising retailers to be extra vigilant about suspicious credit card use; "particularly if an individual attempts to use a number of failing cards or card details one after another for cashback."
CCTV is currently being examined as part of the investigation.
