Two men arrested after a Garda raid on a suspected dissident republican bomb factory have been found guilty of possessing explosive substances.
They are Conan Murphy, 25, from Plaster, Dundalk, and Philip McKevitt, 58, from Aghaboys, Louth.
At Dublin Criminal Court, they denied having a trailer and two gas cylinders adapted to cause an explosion.
Murphy is the son of Colm Murphy who was acquitted on appeal of conspiracy to cause the 1998 Omagh bombing.
The men were arrested in Dundalk in May 2010.
However, giving the verdict on Friday, presiding judge Mr Justice Paul Butler said in light of Garda surveillance and other evidence, the court was "satisfied beyond doubt" that both men were aware of the true nature of the objects.
Gardai discovered an advertising trailer, which had been adapted to conceal gas containers modified to cause an explosion, when they raided Philip McKevitt's home on 22 May 2010.
Both men were remanded in custody and will be sentenced next month.
