On 12 July the Gardaí seized €1.1m worth of cocaine and arrested three men at Dublin Airport with support from German and South American police and revenue officers. Investigations are still ongoing. The previous day, an Uzi machine gun, silencer and two magazines of ammunition were found in Dublin, the second such discovery since March. Before 2012 the guns were issued to the Gardai. The weapons will be analysed to establish if they were used in any recent attacks. No arrests have been made and the investigation is continuing.
