A man has died from his wounds after an overnight shooting in Finglas in Dublin.
Michael Murray, 41, was shot in the head in Kippure Park at around 11.30pm.
He was taken to Connolly Hospital Blanchardstown where he was pronounced dead at around 3am this morning.
The scene of th eshooting is being preserved for forensic examination.
Gardaí are appealing for information on a Fiat Punto that was seen in the area around the time of the shooting.
Michael Murray, a father of three, was a known gunman and named in court last December as the person who shot dead a 25-year-old man in Blanchardstown in a case of mistaken identity.
He is the seventh gang-related murder victim so far this year, but the 41-year-old was warned by gardaí that his life was in danger.
There had been two previous attempts on his life in the past three months and he had been shot and injured in those attacks.
His murder is linked to an ongoing feud among criminal gangs in which a number of other criminals have been murdered.
Michael Murray was named in court just last December as the man who shot Ian Tobin in Blanchardstown in 2007.
The man who drove Michael Murray to the shooting, Bryan Ryan, is the partner of his daughter and father of Michael Murray’s grandchild and is serving life in prison.
Michael Murray is believed to have been killed as part of an ongoing feud which also took the lives of Paul 'Farmer' Martin and Graham McNally.
Today gardaí arrested six people for questioning in relation to these two murders, a development which they describe as significant.
In a separate development, gardaí investigating the murder of Stephen O’Halloran, who was shot dead in Kilmartin Drive in Tallaght last January, have searched three houses and arrested a 20-year-old man for questioning.
Last night's shooting in Finglas was the second gun attack in the area this week.
A man in his 20s remains in a stable condition in Connolly Hospital after a shooting on Monday night.
