Liam Campbell is an Irish republican from Dundalk, County Louth, Republic of Ireland.
His brother Sean died in December 1975, when a landmine he was preparing for an attack on the British Army exploded prematurely. Another brother, Peter, served 14 years in prison for Provisional Irish Republican Army offenses. Yet another brother, Michael, went on trial in Vilnius, Lithuania, accused of trying to purchase arms and explosives for the Real IRA, was found guilty and sentenced to twelve years in jail, a conviction that was overturned with the defendant acquitted upon the completion of a retrial in 2013, largely due to the defence’s argument that Michael was the subject of entrapment, by MI5 agents.
Liam Campbell first came to the attention of the British and Irish security forces in the early 1980s and became the subject of an exclusion order in 1983 barring him from entering Northern Ireland.
Campbell was named by the BBC as one of the perpetrators of the 1998 Omagh bombing in a Panorama documentary. He never faced criminal charges but was found liable for the bombing in a civil trial, along with Michael McKevitt, Colm Murphy and Seamus Daly. The case, brought by relatives of the 29 victims, resulted in an award of combined damages of over £1.5m. He was believed to be a member of the Real IRA army council during the bombing.
