Four men are due to appear in court this morning, in relation to organised criminal activity in Dublin.
The men, who are aged in their 30s and 40s, were arrested yesterday morning.
The men were taken into custody after Gardai stopped and searched two cars in Stoneybatter, where a large knife and balaclavas were recovered.
During a search of one of the cars, a Taxi, two men were found hidden in the boot.
