A 33-year-old criminal was shot in the leg in his own home yesterday afternoon as part of a "deeply personal dispute", the Herald can reveal.
Notorious thug Michael Brennan was recovering from his injuries last night at Beaumont Hospital after being shot at 2pm in the property at Cromcastle Drive, Kilmore, north Dublin.
He was targeted in a downstairs room of the house by a lone gunman in what senior sources say is "more than likely a punishment attack or a warning".
"Brennan is a criminal who is extremely well known to gardai but he is not suspected of being involved in the wider gangland disputes in that locality," a senior source added.
"Instead, gardai are working on the theory that he has been involved in a row with someone who is very well known to him , but this incident was not an attempt to murder him."
There have been no additional arrests following the city's latest gun attack, which is being investigated by Santry gardai.
They yesterday appealed to the public for information about the gun attack.
"A man in his 30s was injured in the shooting and was taken by ambulance to Beaumont Hospital where his injuries are described as non-life-threatening," a garda spokesman said.
"The scene was preserved for technical examination."
Brennan is the younger brother of John Paul Brennan (40), who has survived a number of attempts on his life, including when he was cornered in his girlfriend's home in Kinsealy and shot in the leg and neck in January 2009.
Both brothers were previously closely linked to major drugs trafficker Paul 'Burger' Walsh (37), from Baldoyle, who made a major settlement with the Criminal Assets Bureau in October 2007.
Yesterday's victim was jailed for 10 years in March 2010 for attempting to murder another man over a €200 drug debt.
Drug addict Brennan was convicted by jury in December 2009, of the attempted murder of James Egan and of possession of a sawn-off shotgun.
The jury had heard that he was a teenager when he went to Mr Egan's home and carried out the organised shooting on April 29, 2006.
Then, in November 2010, Brennan was given a further six-year jail sentence - which he served concurrently with the 10-year term for attempted murder - for intimidating witnesses in the 2009 trial.
He admitted that he intimidated a woman who was to give evidence at his trial, telling her if she took the witness stand "she will be put in another box".
The criminal, who has more than 70 previous convictions, pleaded guilty at Dublin Circuit Court to possession of a knife at Cromcastle Drive, Kilmore, on January 7, 2016.
The court heard he had been released in May 2015 from the 10-year attempted murder sentence imposed in 2010.
He was spotted by gardai chasing a group of people while armed with knives.
He chased them to a parked car and appeared to be attempting to open the door or stab the car when ordered to drop the knives.
