Gardaí in Dublin are continuing to quiz a group of four men after a crackdown on organised crime in the city yesterday.
Two of the men were arrested after they were found hiding in the boot of a taxi.
They were discovered when members of the Organised Crime Unit and Garda National Drug Unit stopped and searched two cars on Harold Road in Stoneybatter.
Officers also found a large-bladed knife and balaclavas during the searches.
The three men in their 30s and one man in his late 40s are being held at Mountjoy and Store St. Garda Stations.
