A man arrested as part of an inquiry into the murders of two police officers almost 30 years ago has been released pending a report to prosecutors.

Royal Ulster Constabulary detective constables Michael Malone, 35, and Ernest Carson, 50, were killed in an IRA gun attack on 26 August 1987.

Another officer and a civilian were wounded in the shooting in the Liverpool Bar on Donegall Quay.
