BBC News By Julian O'Neill Published Loyalist killer Michael Stone has been released from prison on parole, BBC News NI understands. One of the most notorious paramilitaries of the Troubles, he killed three people in an attack at Milltown cemetery in 1988. They have been informed of the move. It is understood Parole Commissioners took the decision on Monday and he was freed from Maghaberry Prison on Tuesday. Before now, he had not been due for release until 2024, having failed in an earlier parole bid. After being freed under the Good Friday Agreement, he was sent back to prison after entering Stormont armed with explosives and an axe in an attempt to murder Gerry Adams and Martin McGuinness.
