Detectives investigating alleged dissident republican meetings that were bugged by MI5 have arrested three more men.
Two of the suspects, aged 41 and 54, were detained in the Newry area of Co Down while the other, aged 44, was arrested in the South Armagh area.
Last month, 12 men were arrested in a dramatic raid by heavily-armed police on a house in Newry.
Seven of those were charged with a series of terror offences while the other five were released pending reports being sent to prosecutors for assessment.
During subsequent court appearances, it was revealed that the house in Ardcarn Park that was raided had been under security services surveillance for three months.
During that time, the prosecution alleges, a number of Continuity IRA leadership meetings were recorded. The court was also told that detectives were still actively searching for a number of other individuals allegedly recorded during the meetings.
This morning’s arrests were carried out by detectives from the Police Service of Northern Ireland’s (PSNI) serious crime branch.
Detective Superintendent Kevin Geddes said they were detained in relation to dissident republican activity.
The officer said the suspects were taken to the PSNI’s serious crime suite in Antrim town for questioning.
