A MAN arrested in connection with an IRA bomb attack that killed a Catholic nun and three RUC officers in 1990 has been released pending report to the Public Prosecution Service.
The 55-year-old was arrested in Armagh on yesterday by detectives from the PSNI's Legacy Investigation Branch on suspicion of a number of offences including the four murders.
Sister Catherine Dunne (37), Constable William Hanson (37), Reserve Constable Joshua Willis (35)and Reserve Constable David Sterritt (34) were killed when a landmine exploded on the Killylea Road, Armagh, on July 24 1990. Another woman who had been travelling in the car with Sr Dunne, was seriously injured in the blast.
The pair had been travelling towards Armagh city in a white Mini Metro car when the bomb exploded, sending the car spinning into a ditch.
Sr Dunne, a member of the Sisters of St Louis Order, was deputy director of St Joseph's Training School in Middletown.
She was pulled from the wreckage alive but died soon after in hospital.
Her passenger was also a member of staff at the school, which had 30 girls as students.
The three RUC officers had been travelling in a grey Sierra Sapphire car. The vehicle, which took the full force of the blast, was flung over a high hedge and landed on its roof in a neighbouring field.
The bomb left a crater measuring 30ft wide and 20ft deep. It was reported that around 1,000lbs of explosives had been packed into the ditch.
It later emerged that a family, including young children, had been held hostage in their bungalow in the area, which overlooked the road. It is thought the bomb was detonated using a command wire which had been run across a freshly-cut hay field to a trigger.
A man claiming to represent the IRA later phoned the Irish News to claimed the "Second Battalion, North Armagh Brigade" had been responsible for the "military action".
The man was taken to the Serious Crime Suite at Musgrave Police Station in Belfast yesterday for questioning before being released pending a report to the PPS.
