Two men have been arrested as part of the investigation into the murder of Paul Quinn near the border in Co Monaghan.
The PSNI says the men are being questioned at Antrim Police Station.
Mr Quinn, 21, from Cullyhanna in south Armagh. was beaten to death at a farm shed at Oram near Castleblayney in October last year.
A number of arrests have been made by police on both sides of the border as part of the ongoing investigation but so far no-one has been charged in connection with the killing.
