A man has been arrested in connection with the murder of Paul Quinn in Co Monaghan last year.
Mr Quinn (21) from Cullyhanna, Co Armagh, was beaten to death by masked men wielding iron bars and pickaxe handles after he was lured to a cattle shed near Castleblayney in October 2007.
The man, who is in his 30s, was arrested in Co Monaghan last night. He is being detained at Monagahan Garda Station under Section 30 of the Offences Against The State Act. He can be held for up to 72 hours.
He is the fourteenth person to be arrested and questioned in connection with the murder.
