A tenth person has been arrested by police in the North investigating the murder of Paul McCauley in Derry.
He was beaten and left in a vegetative state in the summer of 2006 after a barbeque in the Waterside area of the city.
He died last June.
A 26 year old man was arrested in Coleraine this morning, while a 26 year old arrested yesterday remains in custody.
This brings the number of arrests this year to 10 - one person has been charged with murder, another has been reported to the PPS.
