Gardai seized more than €1m worth of ketamine following a series of searches carried out in the wider Dublin area yesterday.
More than €100,000 worth of ketamine was discovered after gardai carried out a 'stop-and-search' in Chapelizod Village in Dublin yesterday.
Three men, aged 18, 32 and 36, were arrested at the scene.
The two cars were stopped in the village yesterday evening, shortly after 5pm, as part of an ongoing operation by the Drugs and Organised Crime Bureau.
Both cars were searched at the scene and gardai recovered 2 kg of ketamine with a street value of €140,000.
Follow up searches were then carried out in Dublin and Kildare, where a further 17 kg of ketamine was discovered in a self-storage facility in Straffan.
The total value of the seizures represents the largest seizure of this particular synthetic-controlled drug in Ireland to date, and one of the largest this year in Europe.
