Gardaí have seized an estimated €592,000 worth of suspected cannabis herb in Co Roscommon.
The drugs were discovered during the search of a house in the Frenchpark area this afternoon.
Gardaí say a "sophisticated growhouse" was uncovered in the house and in sheds on the property.
139 cannabis plants and around 22.5kg of vacuum-packed cannabis herb was recovered.
A man in his 20s was arrested and he is being held at Castlerea Garda Station.
