A 36-year-old man has been charged with terrorism offences in connection with the murder of prison officer David Black.
He is due to appear at a Lisburn court on Thursday.
Mr Black, a 52-year-old father of two, was shot as he drove to work on the M1 in County Armagh on 1 November.
He had been driving to his work at Maghaberry Prison, Northern Ireland's high security jail.
A man, 44, and woman, 31, were arrested in Dublin on Tuesday.
Mr Black was the first prison officer to be murdered in Northern Ireland in 20 years.
A new dissident republican paramilitary group calling itself the IRA admitted the killing.
