A man arrested by detectives investigating the murder of Co Armagh pensioner Eugene Carr has been released unconditionally.
Mr Carr (73), who was disabled, was stabbed 15 times while asleep in his bed at his Bessbrook home in August, 2015. It is believed three masked men carried out the attack.
Earlier this month, Mr Carr's daughters offered a £10,000 reward for information that will lead to convictions, which was matched by the charity Crimestoppers for an overall reward of £20,000.
A man aged 35 was arrested in Coleraine yesterday on suspicion of Mr Carr's murder and questioned by detectives. He was released unconditionally last night.
Detective Chief Inspector Eamonn Corrigan said: "Eugene was a father and grandfather and he died in the Royal Victoria Hospital on November 17, 2015 as a result of injuries he received when he was attacked while in his bed at his home in Clogharevan Park, Bessbrook.
"There is a £20,000 reward for information leading to a successful prosecution - £10,000 from Crimestoppers and £10,000 matched by Eugene's three daughters."
Anyone with any information regarding Mr Carr's murder is urged to contact police on 101.
