A major law enforcement operation targeting dissident republican activity in Ireland has led to the arrest and court appearance of a 25-year-old law student, who now faces serious explosives possession charges following the interception of a vehicle carrying a viable explosive device.
The stop and search operation unfolded Wednesday on the N2 highway at Aclint, located just south of Carrickmacross in County Monaghan, where Irish national police, known locally as gardaí, intercepted the car driven by Isobella Perrie Sullivan. Sullivan, a resident of Abbeylands Park in Clane, County Kildare, was taken into custody immediately after the search uncovered a bomb hidden inside a bag stored in the vehicle’s rear. Members of the Garda Special Detective Unit told the court the device recovered contained key explosive components: a timing power unit, a detonator, and materials that officers suspect to be Semtex, a widely known military-grade plastic explosive. After the discovery, the Irish Defence Forces were dispatched to the scene to assess the device, confirming it was a fully functional, viable bomb.
Garda officials confirmed to reporters on Friday that the interception was part of a pre-planned operation focused on disrupting dissident republican activity, a longstanding source of security concern on the island of Ireland. Sullivan was brought before a special sitting of Trim District Court in County Meath on Friday evening to face formal charges of unlawful explosives possession.
The defendant’s legal representation offered context for her involvement, telling the court that Sullivan had been asked to transport the bag to Northern Ireland, and had no prior knowledge of the dangerous contents hidden inside. The solicitor also noted that Sullivan lives with her father in County Kildare, is currently enrolled in a law degree program, and has aspirations to work as a barrister after graduating.
In a bail ruling, the judge outlined that he would approve Sullivan’s release on bail conditional on a series of strict requirements. She must first secure an independent surety worth €15,000, approximately £12,800. Additional terms include surrendering her passport to authorities, complying with a mandatory daily curfew, providing her active contact number to gardaí, and checking in daily to sign the registrar at a local garda station in her home County Kildare. Ahead of the final approval of her bail application, Sullivan has been remanded in custody, with a further bail hearing scheduled to take place on Monday.
