Philip O’Driscoll, from Marsh Road, Skibbereen, died of head injuries sustained during a row last St Stephen’s night.
Last Thursday a Scotland Yard unit arrested a man whom gardaí were seeking in connection with Mr O’Driscoll’s death.
The man, believed to be in his early 40s, was arrested in Swansea and was then taken to London where he is being held until he can be handed over to the gardaí.
At the end of last August the DPP directed that the man should be charged with manslaughter.
However, he had by that time left the country.
Mr O’Driscoll died from injuries he sustained during a roadside altercation.
Gardaí discovered that earlier that day he had left Skibbereen to go drinking in Drimoleague.
He had been in the company of two men and a woman. However, they all left Drimoleague after an altercation when they were refused entry to a pub.
Another row, this time alleged to have been between themselves, broke out as they drove back to Skibbereen.
It is believed that the fight broke out after the car stopped near Gurranes, on the main Drimoleague to Skibbereen road around 7.30pm.
Around half-an-hour later emergency services were called to a caravan at Marsh Road, where they found the settled Traveller dead.
Mr O’Driscoll was unconscious and he was pronounced dead a short time later. A post mortem examination showed that Mr O’Driscoll died from head injuries.
