The PSNI have arrested two men over the murder of 55-year-old Stephen Nelson.
The two men were arrested this afternoon in Newtownabbey, Co Antrim.
Mr Nelson, a Downtown Radio producer, was viciously assaulted on September 19 outside the Chimney Corner Hotel outside Glengormley.
He died from his injuries on March 18 last.
In its report published in May, the Independent Monitoring Commission blamed the UDA for his murder.
Chief Inspector Ian Gilchrist said: “This was a particularly brutal murder which I believe was carried out by members of the UDA.”
At least eight men have previously been arrested for questioning about the attack, all later released without charge.
When Mr Nelson died after six months in a coma, police revealed a £5,000 reward had been put up anonymously in a bid to identify his killers.
