Police in the North have released a man arrested earlier this week in connection with the murder of south Armagh man Paul Quinn last year.
The man, who was detained in south Armagh on Tuesday morning, was the 11th person to be held in connection with the murder in just over a week.
All 11 have subsequently been released without charge.
Mr Quinn, aged 21, was beaten to death by a gang of men after being lured to a remote farm in Co Monaghan last October.
