Garda bug planted in pub foiled bomb bid to kill Prince Charles
Real IRA boss McGrane recorded planning attack on royal visit in 2015
Real IRA leader Seamus McGrane was bugged by gardaí as he plotted in a well-known Dublin pub with another man to carry out an operation involving explosives during the run-up to the State visit of Prince Charles two years ago.
The Garda National Surveillance Unit planted a sophisticated listening device in the snug of the Coachman's Inn on the Airport Road, which recorded conversations between McGrane - a founder of the Real IRA - and engineering graduate Donal O'Coisdealbha.
McGrane (63), from Dromiskin in Co Louth, is only the second person to be convicted of directing a terrorist organisation in the State.
His former colleague and fellow founder of the Real IRA Michael McKevitt was jailed for 20 years in 2003 for directing terrorism between August 1999 and October 2000. He was released from prison in 2016.
During McGrane's trial at the Special Criminal Court, the court heard recordings of the conversations between McGrane and O'Coisdealbha in April 2015.
McGrane told O'Coisdealbha: "Go with whatever plan you wish. I think he's coming on the 19th (a reference to the prince)". I don't like an embarrassment." McGrane then mentioned "military significance".
"Symbolic," O'Coisdealbha replied. "Symbolic is right," replied McGrane. The two men were heard in the recording of April 19 discussing a location "around 400m from the target".
Detective Sergeant Padraig Boyce said that the location being discussed was approximately 400m from the Cross of Sacrifice, a monument in Glasnevin Cemetery commemorating British and Irish soldiers who fought in World War I.
The two men were also recorded discussing a bomb found on a train line in Northern Ireland in February 2015 and an attack on MI5 Headquarters in London in April, 2010.
The court also heard that gardaí found bomb-making components in a field adjacent to McGrane's house.
Veteran republican McGrane joined his former colleague in the Provisional IRA Michael McKevitt at the formation of the Real IRA at a meeting in a remote farmhouse near Oldcastle in Co Meath in November, 1997.
The two had resigned from the Provisional IRA, where McKevitt was quartermaster general, when the terrorist organisation decided earlier that year to begin decommissioning of its arsenal.
At the formation meeting of the Real IRA, McGrane was appointed director of training for the new dissident organisation.
McGrane had been convicted of IRA membership in 1976 but had not been imprisoned since then.
A former member of the Provisional IRA executive, McGrane personally oversaw the training of new volunteers in the Real IRA.
It was during one such training session that he was arrested when the Emergency Response Unit surprised a group of 10 men and boys at a remote farm near Stamullen, Co Meath, in October 1999.
The group, which included Alan Ryan, the Real IRA leader who was shot dead in Dublin in 2012, was weapons training in a disused underground cellar. Gardaí discovered an assault rifle, a sub-machine gun, a pistol and a rocket launcher and ammunition in the cellar.
McGrane was jailed for four years by the Special Criminal Court in 2001 after he pleaded guilty to training others in the use of firearms.
O'Coisdealbha was a significant recruit for the dissident republican terrorist group known as the Real IRA.
His father's background as a former leading Provisional IRA figure, combined with his technical skill and clean record, made him a natural for recruitment by the dissident republican groups who pose the biggest threat to security, north and south of the Border.
Security sources stress that he was not "radicalised" by any outside influence but was easily influenced by older militant republicans because of his natural sympathy for physical force republicanism.
His father, James Monaghan, was one of the so-called 'Colombia Three' who was arrested in Colombia in 2001, convicted of training Farc guerillas in bomb-making and who fled to Ireland in 2004.
Monaghan escaped from the Special Criminal Court following a bomb explosion there in 1976 and was alleged to be the head of engineering of the Provisional IRA, where he gained the nickname "Mortar" Monaghan.
Although O'Coisdealbha never came to the attention of gardaí, who regularly monitor new faces in the ranks of the dissidents, he was soon active in radical causes.
He also took part in the riots in Dublin's O'Connell Street that followed the planned Love Ulster parade in the city in 2006 and he was drawn into the company of dissident republicans and in particular McGrane.
One security source said of O'Coisdealbha: "He was never on the radar of gardaí, but he was a big find for the dissidents because he had the sort of technical knowledge they crave to make explosive devices."
Since his jailing last year, O'Coisdealbha has been on the landing in Portlaoise Prison reserved for the so-called New IRA.
