Gardaí in Donegal have seized 33kgs of cocaine, worth an estimated €2m.
The drugs were found concealed in the panels of a van brought in from the UK.
A search was carried out in Milford after gardaí became suspicious when no one came to claim the van.
They suspect the drugs were being imported to also supply the demand for cocaine in Northern Ireland.
Searches are continuing tonight, but no arrests have been made.
