Four men remain in custody in County Kildare after cannabis worth a million euro was seized.
Gardai stopped and searched two vehicles during the early hours of yesterday morning, where they found 10 kilograms of the drug.
Another search took place at a premises in the Kildare area later in the day, where officers found a 'sophisticated' cannabis grow house.
Over a thousand plants have been seized from that property, with the total value of both finds at about a million euro.
Men in their teens, 20s, 30s and 50s were arrested in connection with the operation.
