A man in his 40s was arrested last night by the PSNI in relation to the fatal shooting of Danny McKay in Newtonabbey, Co Antrim, last month.
The 45-year-old from the New Lodge area of Belfast was taken to the Antrim Serious Crime Suite.
Mr McKay (36) was shot several times in the living room of his home at Longlands Road in Newtownabbey on the outskirts of north Belfast. His funeral took place last Friday.
People in the area at the time of the shooting claimed a number of children were standing only yards away when a gunman opened fire. At least two men are believed to have been involved in the killing.
