There are fears that last night's shooting in Ballymun could lead to retaliation attacks.
Patrick Lyons, who was in his 40s, was shot dead on Belclare Terrace in Ballymun.
At around 9pm last night in a cul-de-sac on Belclare Terrace, a gunman approached Patrick Lyons and fired five shots.
The father of one died at the scene. His remains were removed overnight and a post mortum is being carried out today.
Many locals say they weren't shocked when they heard about the shooting.
Patrick was known to Gardaí but not for serious crime and is not a member of a gang. A motive for the attack has yet to be established, but Gardaí believe it may be related to a personal dispute.
Photos and videos of the immediate aftermath of the murder were posted on line.
Gardaí are urging people not to reshare the footage out of respect to the victims family.
