Two rocket launchers and an assault rifle were seized today by detectives targeting the activities of a criminal gang.
Nine kilos of cocaine, with an estimated street value of €630,000, was also discovered in a warehouse in the Clane area of Kildare, reports the Irish Independent.
Gardai from the Organised Crime Unit searched the premises after four men were charged yesterday under tough laws to combat gangland crime.
The army's bomb disposal squad was at the scene.
Gardai said officers stopped a car on the Naas Road yesterday and detained two men when a kilo of cocaine was found.
Two more men were arrested in a follow-up search operation in the Rathcoole area and all four are being questioned at Clondalkin Garda Station.
A garda spokesman to the Press Association: "As part of a follow-up operation today, gardai from the Organised Crime Unit, assisted by units from Kildare, searched a warehouse in the Clane area of Kildare.
"Nine kilos of cocaine with a street value of €630,000 (subject to analysis) was seized together with an assault rifle and two rocket launchers (subject to technical examination)."
It is understood the seizures and arrests are linked to a south Dublin drugs gang.
