Michael Campbell at an earlier hearing
The trial of a Dundalk man accused of trying to buy arms for the Real IRA in Lithuania has heard evidence from a Lithuanian intelligence agent.
Michael Campbell, 36, was arrested in 2008 in a sting operation in Vilnius.
On Monday an agent involved in the sting gave evidence in a closed hearing.
The trial judge has ruled that security-sensitive evidence must be given behind closed doors.
Mr Campbell was detained while allegedly meeting an undercover Lithuanian agent posing as an arms dealer.
His defence lawyers claim he was set up and that the case is groundless.
