Loyalist serial killer Michael Stone has said poor health means he is no longer a threat to anyone and should be released from jail.
Last week, Milltown Cemetery killer Stone secured a legal route to the Supreme Court in his bid to overturn a verdict that he must remain in jail until 2024.
The 63-year-old ex-UDA hitman, who was jailed for six murders, was freed early under the terms of the Good Friday Agreement in 2000.
Six years later, however, he was returned to jail after attempting to enter Parliament Buildings at Stormont, armed with explosives, knives and an axe, in an attempt to murder Sinn Fein leaders Gerry Adams and Martin McGuinness. Stone denied it had been a bid to kill the politicians, instead claiming it was "performance art".
He is attempting to appeal a decision that the six years he spent out on licence should not count towards his minimum term of imprisonment.
In a statement from his Maghaberry Prison cell given to the Sunday Life, Stone wrote: "I am not the lively 30-year-old that we see on TV running through Milltown. I am a 63-year-old man with heart, blood pressure and mobility issues related to my muscular dystrophy.
"In fact when coming out for paroles or even to attend a weekly visit, I was transported in a minibus with a wheelchair hoist.
"I can no longer manage steps and risk an irreparable injury if I were to fall. Further prison time would only be detrimental. I am no danger to anyone."
