Sean O'Callaghan

Sean O'Callaghan is a former member of the Provisional IRA, who left the organisation in 1975 sickened by its brutality and sectarianism. In 1979 he re-joined but this time working voluntarily as an agent for the Irish police from then until 1985 when he was forced to leave Ireland. In 1988 he walked into an English police station and admitted his involvement in IRA activities in Northern Ireland in the mid-seventies, including the murders of two members of the security forces. He was sentenced to life imprisonment and released in 1996 under a Royal Prerogative. Following his release from prison, he published his memoirs, The Informer: The True Life Story of One Man's War on Terrorism. He now advises a range of institutions on terrorism and extremism and works with young people at risk of getting involved in violent crime.
