A man has been arrested as part of the ongoing investigation into the murder of Paul Quinn.
The man, who is in his 30s, was arrested in Co Monaghan earlier this evening.
He is being questioned at Monaghan Garda Station and can be held for up to 72 hours.
So far 14 people have been arrested by gardaí and PSNI since Mr Quinn’s death in 2007.
The 21-year-old was beaten to death by a gang of up to 10 masked men in October last year.
