Bricklayer Seamus Daly has been released from prison after his prosecution for the Omagh bomb attack collapsed before it reached trial.
The case against Mr Daly, who was charged with murdering 29 people in the 1998 Real IRA outrage, was dropped in court on Tuesday morning.
Mr Daly, 45, had been on remand in prison since being charged with the atrocity and a range of other terror offences in April 2014.
The Co Armagh man walked free from Maghaberry high-security prison in Co Antrim just before 3pm, declining to make public comment before being driven away by family members.
