A Hutch mob hitman issued chilling threats to the two criminals who are the chief suspects for last week's feud murder of Gareth Hutch just hours after the brutal killing.
The same hitman had previously warned that the capital's deadly feud would not end until Daniel Kinahan was shot dead.
Last night, gardai charged one of the two men suspected to have been involved in the Hutch murder in connection with the offence. The 29-year-old will appear at a court sitting today, charged with possession of a firearm in relation to the inner city murder.
The Herald can reveal that a rival criminal alligned to the Hutch gang rang both suspects on their mobile phones shortly after the murder of Gareth Hutch (35) on Tuesday morning of last week.
"You are both dead, I know you did it, I'm going to have you shot," it has been claimed the suspected assassin warned the men, both of whom he knows.
It has emerged that by that stage the identities of the alleged killers had spread around the north inner city like "wildfire."
Shortly after this, the 29-year-old north inner city man handed himself in to investigating detectives in Mountjoy Garda Station at the urging of his mother after armed gardai raided their home in the Summerhill area of the capital.
A woman also questioned by gardai following the inner city gun attack has been released from custody.
The Herald has also learnt that the 29-year-old in garda custody is facing a "grave threat" from a former close associate of his who is currently serving a life sentence for murder in Mountjoy Prison.
Sources have revealed that the 35-year-old convicted killer has warned that he will "organise" his former pal's murder if he is put into the prison system.
It is understood that this threat originates from the gangland murderer's "friendship" with a number of key players in the Hutch mob going back to his childhood in the north inner city.
However, sources say the biggest threat the 29-year-old faces is from the feared criminal who called his mobile on the day of the murder.
The Hutch mob hitman is suspected of being one of the gunmen armed with AK-47's who stormed the Regency Hotel and shot dead rival gangster David Byrne in February's high-profile gun attack.
It previously emerged that the assassin warned gardai that the gang war between the Christy Kinahan cartel and the Hutch mob will not end until Daniel Kinahan is shot dead.
The chilling comments were made when officers raided his northside Dublin home in February.
This notorious north inner city criminal is suspected of carrying out the murders of Paul Kavanagh last year, as well as Eamon 'The Don' Dunne in 2010, on behalf of the Kinahan cartel.
However, he cut ties with the gang after the murder of his close pal Gary Hutch last September and is now their sworn enemy.
In the aftermath of Gary's murder, sources revealed that the hitman refused to attend a number of meetings which the cartel attempted to organise with him because he was "disgusted and heartbroken" about what happened to his pal.
He has been mostly based in Dublin since the hotel murder but has also spent time in Northern Ireland.
Sources said that he was spotted in Dublin's north inner city last week "driving around and not looking very security conscious."
Gardai believe that if the Hutch gang are to organise a "spectacular attack" on their bitter cartel rivals, this criminal will be heavily involved in organising it.
Officers in Crumlin and Dublin's south inner city remain on "red alert" with constant armed checkpoints because of fears the 'spectacular' could happen and might even involve a bomb attack.
Meanwhile, there is expected to be a huge armed garda presence for the funeral of Gareth Hutch which is expected to take place later this week but details have not yet been finalised.
