Two suspects have been arrested by gardai about a botched hit on a car dealer after their DNA was found on airbags in the stolen car that rammed into the victim's BMW.
The two men, who are from the Ballyfermot area and are known heroin addicts, are suspected of being paid to murder Michael Frazer at Islandbridge, south Dublin, on November 1.
The botched shooting was the fourth different attempt on Crumlin man Frazer's life last year, all of which are believed to have been organised by a major drugs trafficker in the 'Fat' Freddie Thompson gang because of a bitter row over women and other issues.
The arrested duo, who are both in their 30s, were picked up by detectives and were being questioned at Kilmainham and Irishtown garda stations over the attempted murder.
"These two individuals are nobodies in terms of organised criminality but are well known to gardai because of offences linked to their drug abuse," a senior source said.
The two men chased Frazer and fired "a number of shots". Frazer managed to escape into the Bellevue apartments in Islandbridge and was uninjured.
The gunmen were driving a stolen 08-registered red Honda Civic car and they fled on foot through the nearby Memorial Park.
The two suspects were stopped by gardai at this location and arrested and searched, but later released without charge. However, DNA results from the airbag have come back and the pair were arrested on Monday.
Officers believe that Frazer was set-up as he arrived at the scene with an associate of his who drove in a separate vehicle - a van. The van was driven to Islandbridge by a man from Cabra who has been spotted with Frazer in recent months.
Sources said that Frazer and his Cabra pal were due to meet a local gangster who was previously closely associated with jailed Ballyfermot crime boss Derek 'Dee Dee' O'Driscoll before the ramming incident.
Apart from the Islandbridge incident, Frazer has survived three other attempted murders last year - one in Clondalkin last March when he was shot three times, and another in the summer when the gardai's Organised Crime Unit intercepted an assassination team in the South Circular Road area.
The third attempt happened in August when he was lured to a meeting in the car park of a pub in Firhouse, when a masked gunman walked up to his car and then tried to open fire.
But the weapon jammed and Frazer rushed to nearby Tallaght Garda Station.
Gang enforcer Paul Rice was arrested but later released without charge.
And a fifth incident was investigated by gardai from Crumlin Station in August when Frazer caused a major security alert when he made a panicked call to gardai.
He said he saw a man in a balaclava standing outside the Drimnagh house where he was staying, but this was not considered a "credible" assassination attempt.
Car dealer Frazer is originally from Drimnagh but now lives at various addresses.
Frazer, who does not have serious criminal convictions, is no stranger to violence and his family home in Drimnagh has been shot at on a number of occasions and a grenade was even thrown into it in June 2008.
