At approximately 8.30pm last night Gardai carried out a planned search of a house at Ballydonnellan, Corrandulla, Co. Galway.
During the search cannabis plants with an estimated street value of up to €264,000 - pending analysis - were seized.
A male in his late 30s was arrested at the scene and is currently detained under the provisions of Section 2 of the Criminal Justice (Drug Trafficking) Act 1996 at Galway Garda Station.
The raid was part of ongoing operations into the illegal sale and supply of controlled drugs in the Galway area by Gardaí attached to the Galway District Drugs Unit
"These operations use advanced analytical and intelligence methods to disrupt criminals and dismantle their networks," a spokesperson said.
"Drug seizures play a critical role in targeting the livelihood of criminals and reducing their ability to carry out illegal activities. Drug seizures also help protect communities from the devastating impact of drugs and the associated criminality.
