Three men have been arrested by detectives investigating the murder of Stephen Carson in south Belfast.
The 28-year-old was shot dead in his house at Walmer Street on Thursday night as his 26-year-old partner and nine-year-old son watched on.
Police arrested three men, aged 32, 37 and 39 on suspicion of murder following searches in west Belfast on Friday evening.
A firearm was recovered and has been sent for forensic tests while the men remain in custody.
Mr Carson, originally from Turf Lodge, had moved to the area following his release from prison. It is believed he had been under death threat from paramilitaries.
The family were eating a meal at around 10.45pm when the gang burst in.
Mr Carson took cover in a downstairs bathroom but he was shot through the door. He died later in hospital.
Detective Sergeant Kevin Geddes, called the slaying “cold blooded and brutal” and has appealed for witnesses
