People are being warned to be on the lookout for counterfeit bank notes after the discovery of one in Ballina earlier this week.
Gardai say a counterfeit €50 was discovered after being lodged through a bank on Monday in Ballina. It is described as a very sophisticated counterfeit note.
Gardai believe the discovery of this note will not be an isolated incident and it is highly likely there are more in circulation.
The serial number on the note was EO118175484 and that serial number would be the same on any other counterfeit notes.
People are asked to report anything suspicious to their local Garda Station.
