Detectives have seized over €8million worth of drugs after searching a car and a house in Kildare.
Two men have also been arrested as part of the seizure, the biggest drugs bust in the country this year, and are being questioned under drug trafficking legislation.
The operation was carried out as part of an ongoing inquiry into organised and serious crime in west Dublin
Gardai are investigating if at least two significant drugs gangs are linked to the massive haul.
Yesterday detectives stopped and searched a car in Kildare which led to around 60kg of cannabis herb being discovered.
A connected search of a property in the Straffan area also led to 314kg of the drug being recovered.
Meanwhile, gardaí said that cocaine was also seized during the search of a vehicle with a street value of €770,000 bringing to €8.2m the estimated value of all drugs seized.
As part of the investigation two men, aged 49 and 46, were arrested and are currently being held at Naas Garda Station under drug trafficking legislation
They can be held for a period of up to seven days.
Gardai said the seizure was made as a result of an intelligence operation involving personnel attached to the Garda National Drugs and Organised Crime Bureau (GNDOCB) and Special Crime Task Force (SCTF) assisted by members assigned to the Dublin Metropolitan Region (DMR).
Detective Chief Superintendent Angela Willis, head of bureau at the Garda National Drugs & Organised Crime Bureau, said: “The operation undertaken today involving participation by the Garda National Drugs and Organised Crime Bureau and personnel in the DMR, which has resulted in the seizure of illicit drugs with an estimated street value of €7.4 million, demonstrates An Garda Síochána’s continued determination to tackling the supply of controlled drugs, that cause significant harm and misery in our communities.
“We will continue to target those who are engaged in the distribution of illicit drugs and tackle criminality engaged in by organised crime gangs who benefit from such activity.”
Assistant Commissioner John O’Driscoll who is the Head of Organised and Serious Crime said: "The significant success being achieved by members of the Garda Síochána throughout the organisation in tackling serious and organised crime in the challenging circumstances arising from the Covid-19 pandemic, is outstanding and reflects their considerable ability and dedication.”
