Law Student Charged After Viable Explosives Intercepted Near Northern Ireland Border.

The vehicle was stopped on the N2 at Aclint, Carrickmacross, Co Monaghan, very close to the Northern Ireland border, as part of a Garda operation targeting dissident activity.
The bag in the car's rear contained a timing power unit, a detonator and Semtex; Irish Defence Forces attended the scene and described the device as viable.
Bail was set at €15,000 independent surety with strict conditions, including surrender of the passport, an address approved by Gardaí, a 24/7 phone contact, daily Garda sign-ins and a curfew from 9pm to 7am.
Defence solicitor Gavin Booth said the defendant had been asked to take a bag to the North and was unaware of its contents.
The interception sits within ongoing investigations into dissident republican activity and border-security concerns.
Irish law student Isobella Perrie Sullivan, 25, has been charged with possession of explosives after Gardaí stopped a car on the N2 near Carrickmacross, Co Monaghan, close to the Northern Ireland border. A bag in the back seat contained Semtex, a detonator, and a timing power unit — components that Irish Defence Forces confirmed made up a viable bomb. Dayton Daily News described the seizure as an "extremely significant" bomb threat.
Sullivan, from Co Kildare, appeared at Trim District Court and was granted bail of €15,000 under strict conditions. Her defence solicitor said she had been manipulated and had no idea what was in the bag she agreed to carry.
Gardaí stopped the car at Aclint on the N2 as part of a planned operation targeting dissident republican activity. The N2 runs directly toward Northern Ireland, and the device was believed to be heading there. Irish Defence Forces attended the scene and confirmed the bomb was viable. The Journal reported that investigators called the find "extremely significant."
The three components found — Semtex, a detonator, and a timing power unit — are the building blocks of a fully functional explosive device. Semtex is a plastic explosive widely associated with terrorist attacks. A timing power unit allows a bomb to be set off remotely or on a delay, making the device far more dangerous.
Solicitor Gavin Booth told the court that Sullivan was not a knowing participant. He said she had been asked to take a bag to the North and was completely unaware of what it contained. Booth argued she had been manipulated by others.
Sullivan is a law student from Co Kildare, a county more than 100 kilometres south of where she was stopped. The court has not yet heard the full prosecution case. She will face a further bail hearing as proceedings continue.
The court set bail at a €15,000 independent surety — meaning a third party must put up the money. Sullivan must also surrender her passport, preventing her from leaving Ireland. Additional conditions include daily sign-ins at a Garda station and a curfew between 9pm and 7am. She must stay at an address approved by Gardaí and keep a 24/7 contact number active. The Reflector confirmed all conditions were accepted by the defence.
This case fits into a broader pattern of dissident republican activity along the Irish border. A small minority of hardline republicans reject the 1998 Good Friday Agreement, which ended most of the Troubles. They continue to pursue a united Ireland through violence. Authorities on both sides of the border have been monitoring this threat for years. HJ News noted the case is linked to ongoing cross-border security investigations.
Coverage of the case also references the unsolved 2009 murder of Paul Byrne, showing that dissident activity in the region has a long history. The interception of a viable device so close to the border is a reminder that post-Troubles security challenges have not gone away entirely.
