Gardai have warned that high quality forgeries of €20 notes have been moving into circulation across Ireland.

The fake notes have been found in six counties so far: Dublin, Cork, Waterford, Limerick, Kildare and Tipperary.

Gardai have warned retailers and consumers to be vigilant and to carefully inspect notes they receive, in the same way they examine €50 notes.

Gardai believe the forgers are using the notes at major events and festivals.
