Two men have been arrested as part of an international operation targeting the trafficking of drugs into Ireland.
The men, aged in their 30s and 40s, were detained following searches in Dublin and Meath.
Officers from the Garda National Drug Unit, the Garda Organised Crime Unit and local teams carried out the seven swoops, as part of Operation Majesty.
Detectives have been working with police in the Netherlands, Germany and the UK since last year, during which time they have seized 2.5 million euro in cash and 2.5 million euro worth of cannabis.
Grenades, several firearms and ammunition have also been recovered as part of the ongoing operation, which has focussed on the activities of one particular Dutch organised crime gang with strong Irish connections.
The men arrested were taken to Blanchardstown Garda station where they were being held under Section 2 of the Criminal Justice (Drug Trafficking) Act 1996.
Elsewhere, a man was arrested following the seizure of 10,000 euro worth of cannabis in Co Laois.
Two sawn-off shotguns, a pistol and a quantity of ammunition were also recovered in the search of an apartment at the Oaks, Killnacourt in Portarlington this afternoon.
The man, aged in his late 20s, was taken to Portlaoise Garda station and held under Section 30 of the Offences Against the State Act 1939.
