A pensioner being questioned about the murder of a policeman in Northern Ireland more than 30 years ago was released on bail tonight.
The 72-year-old man was arrested yesterday in connection with the killing of 49-year-old RUC Detective Sergeant Joe Campbell outside a police station in Cushendall, Co Antrim, in February 1977.
The development in the unsolved case came a week after officers from the Police Ombudsman's Office revealed they had unearthed a fresh lead.
Ombudsman Al Hutchinson is re-examining the incident after complaints alleging police involvement in the shooting of the Catholic father-of-eight.
An RUC detective sergeant was arrested in the early 1980s and charged with the murder but was later acquitted at Belfast Crown Court.
Mr Hutchinson's team is also looking at claims that the RUC failed to investigate the crime properly.
Mr Campbell was shot with a high velocity rifle as he locked the village police station at around 10.30pm on 25 February, 1977.
He suffered one wound to the head and died almost immediately.
