On 24 November 2006, at 11:16, Stone was arrested for attempting to enter
Parliament Buildings at
Stormont armed with an imitation
Beretta 92FS pistol, a knife and a "viable" bomb, after placing eight "
pipe bombs" within the grounds of Stormont. Three civilian security guards disarmed him as he entered the building, by trapping him within the revolving doors of the main lobby entrance. The security guards were injured during the struggle with Stone. Following the security breach, the building was evacuated and a British Army Bomb Disposal Unit was called to examine the suspect device. Before entering the building he had scrawled an incomplete graffito stating "Sinn Féin IRA mur[derers]" on the Parliament building. Later examination from the bomb squad revealed that the bag Stone had been carrying contained between six and eight viable explosive devices. Sir
Hugh Orde, the
Chief Constable of the
Police Service of Northern Ireland, said "their potential for death, destruction and injury is being assessed" but added they were "fairly amateurish". As a result of Stone's actions, talks between political parties about power-sharing and the election of a First Minister, which had only just resumed, had to be abandoned. On 19 December 2006, Stone's defence lawyer, Arthur Harvey,
QC, claimed that the Stormont incident was not intended to endanger the life of anyone. "It was, in fact, a piece of
performance art replicating a terrorist attack", claimed Harvey. Secretary of State for Northern Ireland
Peter Hain indicated that Stone's licence for release under the Good Friday Agreement would be revoked, and the full 638-year sentence for triple murder and firearm charges be re-imposed on him, in line with his sentencing in 1988. On 25 November 2006, Stone appeared in court in Belfast charged with attempting to murder Sinn Féin leaders Gerry Adams and Martin McGuinness. Stone faced a total of five charges of attempted murder following the incident at Stormont. Stone was charged with possession of articles for terrorist purposes, possession of an imitation firearm in a public place, assault,
grievous bodily harm, possession of an offensive weapon and possession of explosives. The court heard the articles allegedly for terrorist purposes included nail bombs, an axe and a
garrotte. He was remanded in custody until 22 December 2006. On 14 November 2008, Stone was found guilty of attempting to murder Adams and McGuinness. The judge said defence evidence that Stone had been taking part in some sort of a "comic parody" was "hopelessly unconvincing" and "self-contradictory". On 8 December 2008, Stone received a 16-year sentence for his actions at Stormont. In 2013, a Belfast Court of Appeal ruled that Stone had to spend a further 18 years in prison for the killings at Milltown cemetery. He was released on parole on January 26, 2021. A legal challenge by victims' families to prevent Stone from applying for early release from prison was dismissed by the Court of Appeal. ==Personal life==
