A "naive" man who made a “catastrophic error of judgment” by opening the gates of his father’s quarry and allowing the IRA to take explosives away has avoided an immediate jail sentence.

Two men who were “in joint control” of 167kg of explosives found inside a car - enough to make a bomb three quarters as large as the one detonated in Omagh in 1998 - have been jailed for total of 15 and a half years.

A man's denial that he knew anything about 167kg of explosives found inside his "heavily laden" car - including detonators sticking out from the passenger seat - has been found to be "totally incredible" by the Special Criminal Court.

Two Dublin men were stopped by gardaí in a car which was found to contain 150kg of explosives, the Special Criminal Court has heard.
