Louth man jailed over selling US-bought firearms to Irish criminal gangs

Conor O'Brien, a 29-year-old man of Kilpatrick, Ardee, Co Louth, who holds US citizenship, was part of a criminal organisation that bought military-grade firearms in Nevada, smuggled them into Ireland in component parts and sold them to criminal gangs between 10 February 2023 and 19 July 2024. Gardaí raided a shed in Blackstick, Ardee, on 19 July 2024, found the weapons and arrested O'Brien and a co-accused. O'Brien was arraigned in November 2025 and pleaded guilty to six charges. On Monday 16 March 2026 the Special Criminal Court sentenced him to 11 years with the final 12 months suspended, though some reports say ten years, and further submissions on seized cash were due the following week.
