Eamon Collins
Police have arrested a man in connection with the death of IRA man Eamon Collins 15 years ago.
Collins specialised in collecting information on police officers, security services and RUC officers for the IRA.
He was found dead in Newry in 1999 having been run over by a car, stabbed and beaten to death.
A 42-year-old man was arrested in Newry this morning in connection with the the murder.
Before he died, Collins wrote a book called Killing Rage, in which he described life inside the IRA.
He also turned supergrass on the organisation after being arrested in 1985, famously giving evidence against Thomas 'Slab' Murphy in court.
The PSNI have previously stated that they have DNA from the scene of the murder.
"I would ask those with information about Mr Collins' murder, particularly those in the Barcroft estate, to think again about the awfulness of what happened and about the Collins family," said Detective Chief Inspector Peter Montgomery.
"It is never too late to come forward."
While in the organisation, Mr Collins collected information on police officers and Royal Ulster Constabulary special branch members and set up assassinations over a six-year period.
He was arrested in 1985 and charged with 50 terrorist offences including five murders and membership of the IRA.
But he turned supergrass after his arrest, and said he was prepared to give evidence against former colleagues.
Many suspects were arrested but most were released, after Mr Collins changed his mind.
A judge dismissed his alleged confessions and he was freed.
He later wrote a book, Killing Rage, which was highly critical of the IRA.
In January of this year, police said they had DNA obtained from the murder scene.
