Gardaí are continuing to question a man in relation to a fatal attack in the Ballyfermot area of suburban Dublin on Friday.
The man, aged in his 30s, was detained on Friday and is being held under Section 50 of the Criminal Justice Act, 2007, at Ballyfermot Garda station.
Gardaí believe the shooting dead of a criminal at his home in the Ballyfermot area of suburban Dublin is part of an escalating feud in the city between the Real IRA and gangland criminals. The murder was the third gangland killing of the week.
While the investigation into the murder of John Wilson (35) is still in its infancy, the main line of inquiry is that it is a revenge murder for the shooting dead of key Real IRA member Alan Ryan four weeks ago.
Wilson had collected children from school on Friday and left them to another house. He returned to his home in Cloverhill Road, Ballyfermot, just before 3pm. As he went inside he was followed by a gunman who had had him under surveillance. He was shot in the arm and torso. The killer ran to a waiting car and was driven away at speed.
Frantic efforts were made to revive Wilson but he was pronounced dead at the scene. The area was sealed off by gardaí before Wilson’s body was taken away for a full postmortem.
The killing was the 13th gang-related gun murder of the year and comes at a time when such gain attacks are increasing in frequency after a lull in recent years.
