Gardai seized two firearms as part of a major operation against a gang boss who was the intended target of the capital's latest gun attack.
Another man, Mark Ivers (30) is lucky to be alive after he was shot in the chest and leg outside a house in the Streamville Road housing estate in Donaghmede, shortly after 7pm on Friday.
The actual intended target of the attack - a 30-year-old criminal - escaped by hiding inside a bathroom in the house when he saw the gunman.
He was dealt a further blow yesterday when two guns and ammunition linked to him were seized and a 44-year-old close associate of his was arrested.
The arrested man was being quizzed last night at Coolock Garda Station.
A number of vehicles were intercepted by officers from the Emergency Response Unit (ERU) and a search of a premises and communal area was carried out in the Donaghmede area during the intelligence-led operation.
A garda statement last night added: "Two firearms and associated ammunition have been recovered and at approximately 1pm [yesterday], a male aged 44 was arrested and is currently detailed at Coolock Garda Station under Section 30 of the Offences against the State act 1939 as amended."
In July, the Herald revealed that the 30-year-old criminal was arrested as part of an operation in which detectives believe a hit was foiled.
The convicted heroin dealer, along with a 33-year-old low-level criminal, were arrested in the Kilmore area of Coolock and two loaded firearms were recovered in a car close to the family home of slain criminal Sean Little.
The arrested 30-year-old is the chief suspect for ordering the horrific drug debt-related murder of a young man this year, which cannot be outlined for legal reasons.
"This individual has become a huge player in the past year since being released from jail," a source told the Herald.
"He is completely off his head on cocaine most of the time and is ordering shootings left, right and centre."
He is also suspected of being behind two gun attacks on the home of an innocent family in Co Tyrone, after warning a former pal: "I'm going to shoot your Ma."
Only two weeks ago, the gang boss was dealt a major blow when €250,000 worth of heroin owned by him was found after gardai apprehended a young man walking through a Coolock housing estate.
Life has more or less returned to normal in the Streamville Road housing estate in Donaghmede following the shooting on Friday evening.
The brazen shooting took place directly across the street from where local children were playing in a field and secondary students were engaged in band practice at the Donahies Community School.
Local resident Ryan Gibson (25), who rang an ambulance after he saw a local couple with a baby in a pram run for cover after they learned of the shooting, said the area has been "oddly quiet" since the shooting.
"Life seems to have carried on as before. I don't know if it's people getting used to it," he said of the ongoing gangland feuds that have erupted in the capital.
Meanwhile, gardai revealed they are concerned that the latest shooting will lead to more bloodshed.
Sources told the Sunday World that they are very concerned the intended target of the shooting will try to orchestrate more shootings, even though he has been issued with a formal warning by gardai that his own life is at risk.
"He's out of control, but so are the people who are targeting him," a source told the newspaper.
