Revenue has seized two parcels of cocaine worth more than €140,000 in Athlone.
The illegal drugs originated from the Netherlands and were due to be sent to addresses in Louth and Armagh.
Separately, detector dog Milo helped Revenue seize 10,000 illegal cigarettes in Cavan late last week.
The cigarettes arrived from Latvia and a man in his 30s is being questioned over the discovery.
