Senior Government and Garda sources last night said there was no information to support a report in this week's Anglo Celt newspaper in Co Cavan purporting to identify the site of the IRA arms dump where the first act of decommissioning took place.
The sources denied an aspect of the report that a "covert operation" was mounted by special branch detectives in the area where the decommissioning is purported to have taken place.
Senior Garda sources said there was no information about the whereabouts of the IRA arms dump where the head of the Independent International Commission on Decommissioning (IICD) witnessed the "significant" act in which arms and explosives were decommissioned.
The colourful report by the Anglo Celt reporter, Mr Sean McMahon began: "When the detailed history of the peace process is written in years to come, the famous Cavan place names of Maudabawn and Dumgoon will jump off the page."
The report said the IRA arms bunker is "located on a remote farm with a view of picturesque Lough Sillan". The dump "remained intact and undiscovered during the 30 years of Troubles in Northern Ireland".
There is also a purported account of the decommissioning operation. It says the IRA Army Council met in Maudabawn on the morning of the event and then travelled to the bunker in two cars.
"Two other cars sailed through Shercock carrying Gen John de Chastelain, head of the IICD, the former Finnish President Martti Ahtisaari and former African National Congress Secretary General Cyril Ramaphosa.
"Martin McGuinness and his team linked up with the general and his team and they were all whisked off to the remote farmyard."
The report says the decommissioning of the weapons took the form of pouring "fast setting cement" from the Co Fermanagh suppliers Sean Quinn into the underground bunker.
"The concrete was poured into the bunker with great expertise and the entire operation was carried out with precision. It was all completed before dark.
"As the rural Dumgoon countryside returned to normality, the weapons of war were already rusting in peace forever."
