Gardaí have launched a murder investigation after a man was shot dead in Dublin.

The body of the 29-year-old was found on Deanstown Avenue in Finglas at around 4.30am today.

The victim is well known the gardaí for his involvement in organised crime and in an ongoing feud between two gangs in Finglas over control of the drugs trade.

He had previously been close to, but fell out with, a major Finglas criminal whose drugs operation was based in a house seized by gardaí and Dublin City Council in February.

Gardaí are trying to establish the man's last movements and contacts and have appointed a family liaison officer.

They are also investigating a number of shootings in Finglas in recent weeks as part of the ongoing feud, including a gun attack on Friday night near the victim’s mother's house.

A post-mortem examination has been completed this evening by Chief State Pathologist Dr Linda Mulligan at the City Morgue, Whitehall.

Specific details of the post-mortem are not being released for operational reasons, gardaí said.

Gardaí have appealed for witnesses or anyone with information to contact them at Finglas Garda Station on 01 666 7500, the Garda Confidential Line on 1800 666 111 or any garda station.
