Detectives in civil servant killing probe arrest man, 26
A 26-year-old man has been arrested by detectives investigating the sectarian killing of a popular civil servant in Northern Ireland.
Paul McCauley, a 38-year-old Catholic, spent almost a decade in a vegetative state after being beaten by loyalists in Londonderry's Waterside area in 2006.
Police said the suspect was detained in the city this morning and has been taken to Coleraine for questioning.
Detective Chief Inspector Michael Harvey, who is leading the murder hunt, said: "This arrest brings the number of people who have been arrested since Paul died last June to nine.
"To date, one man has been charged with murder and another reported to the Public Prosecution Service.
"Our enquiries into this murder are very much ongoing and I would like to thank those people who have so far come forward to assist us since Paul's death."
Father-of-one Mr McCauley was 29 when he attended the barbecue for a friend who was moving away from Northern Ireland.
A gang of up to 15 people emerged from nearby bushes and attacked him and two friends as they were clearing up after the meal in the early hours of the morning. He suffered severe head injuries.
Police stepped up their investigation following his death last June.
DCI Harvey said: "The momentum in this investigation is continuing.
"Detectives are available to speak with anyone who decides they want to talk to us. Even after nine and a half years, it is not too late to do the right thing and come forward."
Mr McCauley's family has pursued a long campaign for justice.
Piper John McClements, 24, previously known as Daryl Proctor, from the Fountain area of the city, has been charged with Mr McCauley's murder.
