Case No. 10706Firearms and criminal organisation offences · Co. Louth

Man jailed for ten years over guns bought legally in US and sold to Irish gangs

Conor O'Brien, a 29-year-old man who holds US citizenship, was caught with an arsenal of firearms, ammunition and components in a rented shed in Blackstick, Ardee, Co Louth, after using his US citizenship to buy military-grade weapons legally in America and selling them to Irish criminal gangs between 10 February 2023 and 19 July 2024. He was arraigned on six charges the previous November and pleaded guilty to facilitating the importation of firearms for a criminal organisation and to five counts of possessing or controlling firearms or ammunition in suspicious circumstances. In March 2026 the Special Criminal Court sentenced him to ten years in prison and ordered the forfeiture and destruction of the weapons, and the latest development is that further submissions on cash seized from him will be heard the following week.
