Detective Chief Inspector John Caldwell said a 20-year-old man was arrested on suspicion of murder.
“We received a report at around 11.55pm about an incident involving a man armed with a machete outside a house in the Slievecoole Park area of the town,” he said.
“Officers attended, along with colleagues from the Northern Ireland Ambulance Service. Sadly, one of the men, aged 53, who had been administering first aid, died a short time later. Another man was taken to hospital for treatment of injuries to his hand.
“A 20-year-old man has been arrested on suspicion of murder and attempted murder, and is currently in police custody.”
Mr Caldwell urged anyone who was in the Slievecoole Park area or licensed premises in the Gortin Road area on Sunday evening, before or around the time the assault was reported, and who saw what happened to get in touch. -PA
