Killybegs gardaí arrested and detained two people in Donegal Town last night and seized a substantial quantity of drugs.
Both were held over night and released this morning pending a file being sent to the DPP.
Gardaí are satisfied that the drugs were destined for the Killybegs area.
The drugs seized were cocaine and cannabis.
The seizure, while not of national importance, would be deemed to be quite substantial for South West Donegal.
Senior investigation officer Kevin Gilgunn is leading the investigation and he is also acting Sergeant in charge in Killybegs.
Inspector Denis Joyce has again warned of the dangers of recreational drugs.
“The seizure is a result of extensive surveillance and intelligence”, he said.
