A gunman has opened fire at a home linked to an associate of drug dealer 'Mr Flashy' for the second time in a month.
Gardai were called to a house in Finglas on Monday night after receiving reports of a shooting.
The incident occurred in the Cappagh Drive area shortly before 11pm.
When gardai, including members of the Armed Support Unit (ASU), arrived at the scene they discovered spent shell casings on the ground.
However, a number of people who were in the area at the time declined to assist officers.
A garda spokesman told the Herald that no injuries were reported and an examination of the scene was carried out by officers.
Investigators at Finglas Garda Station are appealing for anyone with information to contact them.
It is the second time in just over a fortnight that the house linked to an associate of 'Mr Flashy' has been targeted.
On April 13, a number of shots were fired at the house at around 11pm, but again on that occasion witnesses would not co-operate with gardai.
Detectives are investigating if the shooting is linked to a feud in west Dublin between two criminal gangs. One faction, led by former members of the infamous Westies gang, is being supported by the mob led by a drug dealer known as 'Mr Flashy'.
His 21-year-old associate, targeted in Monday night's attack, is also suspected of supporting this faction.
The rival mob is led by two brothers from the Corduff area who have also been targeted in gun attacks.
A number of shootings have taken place as well as petrol bomb attacks and serious assaults. Gardai have increased armed patrols in the area in recent months.
More than 30 people have been linked to the violence, which has seen a number of people formally warned that their lives are at risk.
Gardai have also seized firearms including pistols, shotguns and a crossbow during crackdowns on the gangs.
Last Friday night gardai recovered a loaded pistol during searches near Riversdale Community College and the Institute of Technology, Blanchardstown.
A loaded Makarov 9mm pistol and silencer were among the items seized in one search, which involved members of the Defence Forces.
The search team also discovered nine shotgun cartridges and four 9mm bullets at a separate location.
