Police in the North have arrested another man in south Armagh this morning as part of the investigation into the murder of Paul Quinn last year.
The PSNI says it also searched two properties in the border area this morning at the request of the Gardaí.
Last week, 10 people were arrested on both sides of the Border as part of the investigation into Mr Quinn's murder last October.
The 21-year-old was beaten to death by a gang of men after he was lured to remote farm in Co Monaghan.
The body set up to monitor paramilitary ceasefires in the North has concluded that the killing was arranged by IRA members and their associates in south Armagh.
