A 21-year-old man has appeared in court charged with withholding information about the murder of a policeman in Co Armagh earlier this month.
The accused, who cannot be named for legal reasons, is charged with failing to provide police with information related to the shooting of Constable Stephen Carroll.
He was remanded in custody by Lisburn Magistrates Court.
A court order prevented any further details of the remand proceedings being published or the reason for his identity being withheld.
A 37-year-old man and a 17-year-old youth have already been charged with the murder.
The 48-year-old constable was shot dead on 9 March in Craigavon, Co Armagh.
He was the first policeman to be murdered in Northern Ireland since 1997
His death came two days after the Real IRA killed two British soldiers in Antrim.
Elsewhere, Taoiseach Brian Cowen has described those responsible for the recent deaths of two British soldiers and a PSNI officer as criminals, not dissident republicans.
Earlier members of Republican Sinn Fein refused to condemn the attacks and described them as regrettable but inevitable 'acts of war'.
The Taoiseach made the comments to journalists at a function in Belfast.
