A GANGSTER was tipped off about the details of a garda intelligence file after the dossier on the gang of murdered boss Eamon Dunne was sent by officers to a Dublin photocopying shop.
The top secret document detailed membership of one of the country's most lethal gangs.
It was seen by somebody in the shop who then informed a gang member that he featured prominently in it.
The dossier was to be delivered to the DPP, who would then have decided whether to bring anti-gangland charges.
The file, which contained information on the gang responsible for murdering Eamon 'The Don' Dunne, was sent to the copying shop on the orders of a senior garda.
It was brought by a garda from Store Street station to the shop and not the official garda photocopying centre in Santry.
Six months had been spent compiling the intelligence, which contained details on about 40 members of the gang.
A chart showed the criminals' position in the hierarchy of the organisation.
However, a person in the shop recognised some of the names on the list and phoned a gang member to tell him.
It was agreed that the caller would keep a copy of the file to pass it on to the criminal.
The conversation was overheard by gardai monitoring a criminal's phone.
Gardai from crime and security and the Organised Crime Unit then descended on the shop and closed it down while they interviewed several people.
The person who passed the information on to the gang was understood to have been quizzed, though no charges are expected.
Eamon Dunne was shot six times in the head and body at close range last April.
Dunne (34), the leader of one of the biggest organised crime gangs in the country, was gunned down in the Fassaugh House pub in Cabra, north Dublin.
Dunne's gang was originally led by Martin 'Marlo' Hyland but he was murdered in 2006 by his own associates.
Under the Don's leadership, his gang imported vast quantities of drugs from outside Ireland and supplied them to smaller gangs nationwide.
Dunne was suspected of helping to organise Hyland's murder as well as a string of other hits.
