A 26-year-old man has been arrested in Derry in connection with an attack nine years ago that led to Paul McCauley's death last June.
In all, nine people have been arrested, one has been charged with murder and another has been reported to the Public Prosecution Service.
The 38-year-old died in a care facility almost nine years after he was attacked by a group of up to 15 people at a barbeque at a house on the Chapel Road on July 15th 2006.
