A senior member of the Kinahan cartel has been taunting gang rivals in the 'New IRA'.
The arrogant thug has been "mouthing off" that the dissident mob are not capable of avenging the murder of republican Michael Barr.
The 34-year-old was shot dead in the Sunset House pub, Summerhill in Dublin's north inner city as part of the bloody Hutch/Kinahan feud last month.
The Herald has learned that the Crumlin thug, who was a close associate of feud murder victim David Byrne, has been telling pals that he is confident that Barr's murder will not be avenged.
"He is even claiming that he could buy-off any potential IRA hitman and that the only loyalty that the IRA have is for cash," a source said.
The Sunset House pub has remained closed since the gruesome murder and has had its name painted over.
Gardai believe father-of-five Barr was murdered because of his possible role in the Regency Hotel gun attack and his close links to the gunman nicknamed 'Flat Cap', who was photographed fleeing the hotel in the aftermath of the murder of David Byrne on February 5.
However, while the Kinahan gangster seems to believe he is untouchable, senior gardai have been maintaining armed checkpoints near his home ever since Barr was shot dead.
Gardai believe there is a "very strong possibility" that Barr's associates in the 'New IRA' will strike back against the cartel, and this has been one of the main reasons for the increase in armed checkpoints.
"They have the means, they have the manpower and they have the weapons. The murdered man was a senior IRA figure, and gardai remain concerned about IRA involvement in the feud," a senior source explained.
Meanwhile, yesterday, at the High Court in Belfast, three Dublin men who are accused of wearing paramilitary-style clothing at last Thursday's funeral of the murdered republican, were granted bail.
Conor Metcalfe, John Christie and Patrick Lavin are to be released from custody on condition they keep out of Strabane in Co Tyrone.
Metcalfe (25) of Monasteoy Park, Dublin, Christie (52) from Ratoath, Co Meath, and Lavin (52) of Deansrath, Clondalkin, are jointly charged with wearing clothing in a way to arouse suspicions they were members or supporters of a proscribed organisation.
Fifteen men were arrested following the service and questioned about alleged membership of a dissident republican grouping known as the New IRA.
Police released 12 of them, pending a report to the Public Prosecution Service.
At a previous hearing, bail was opposed due to tensions in areas of the North, as well as fears the trio would fail to appear in future.
