Irish authorities have charged two individuals with possession of explosives following an intelligence-led operation that intercepted a suspected car bomb near the border with Northern Ireland. The operation, conducted by Gardaí on Wednesday, July 22, 2026, occurred on the N2 road at Aclint, Carrickmacross, in County Monaghan.
Simon O’Donovan, a 44-year-old employee at the Collins Barracks National Museum in Dublin, was remanded in custody after appearing before the Special Criminal Court on Saturday. He faces charges related to the possession of military-grade explosives and a detonator discovered inside a vehicle. A second suspect, 25-year-old law student Isobella Perrie Sullivan, was charged on Friday at the Trim District Court and subsequently granted bail.
During court proceedings, it was disclosed that the device was found in a bag on the rear seat of the vehicle during a targeted stop. Garda Commissioner Justin Kelly emphasized that the intervention was not random, but the result of specific intelligence gathering aimed at disrupting dissident republican activity. According to police, the suspected device had the potential to cause significant damage.
Commissioner Kelly noted that while the Good Friday Agreement largely ended sectarian conflict in the region, a small minority of “radicalised republicans” continue to reject the peace process. Authorities remain on high alert as they investigate the potential links between the suspects and groups that have failed to decommission weapons and explosives following the treaty.
