HUNDREDS of hours of tapes that Stormont's Nama inquiry was told show "illegal conduct" in politics and banking have been handed over to the PSNI.
Officers met yesterday with Gareth Graham and were given access to the thousands of telephone call recordings that until now have been kept under lock and key.
The Belfast businessman last month alleged the tapes revealed an "ingrained culture of inappropriate and possibly illegal conduct" across political, banking, legal and accountancy sectors.
His explosive claims were made as he appeared before a finance committee probe into the scandal-hit Nama Northern Ireland property portfolio deal.
The inquiry was launched following allegations made in the Dáil in July that around £7m linked to the deal was earmarked for a Northern Ireland politician.
Mr Graham was understood to have agreed to meet with the PSNI yesterday along with his solicitor, and officers have also been given access to the recordings.
A police spokeswoman last night said: "PSNI met with Mr Graham this afternoon to discuss a number of issues he raised during his appearance at the Stormont finance committee's Nama inquiry."
It follows Mr Graham travelling to the US late last month to meet with the Securities and Exchange Commission (SEC).
Mr Graham had told the finance committee he had made a complaint to the financial watchdog over "inappropriate political relationships and potentially unlawful banking relationships" disclosed in the tapes.
Loans held by Mr Graham's property companies were within the portfolio sold by Nama last year for £1.3bn to US investment fund Cerberus.
The businessman, a member of the Sean Graham bookmaker family, has been fighting a legal battle with Cerberus in a bid to regain control of his firms.
Last month Mr Graham told the finance committee the recordings include thousands of phone calls made by ex-Nama adviser Frank Cushnahan.
In dramatic evidence he told the Stormont probe that former colleague Mr Cushnahan's appointment to Nama's Northern Ireland advisory committee had directly impacted on his firms.
He claimed Mr Cushnahan was "intent on destroying our businesses", and his firms were wrongly taken into Nama following his former colleague's "malevolent" influence.
Mr Cushnahan has dismissed claims and denied any wrongdoing.
The Irish News revealed the existence of hours of tapes back in July as the Nama scandal emerged following claims by independent TD Mick Wallace.
A criminal investigation led by the National Crime Agency political probes on both sides of the border are ongoing.
Mr Graham told the Stormont probe he had listened to calls, which were recorded for regulatory reasons, between Mr Cushnahan and people including politicians.
He said the recordings were made from 2005 to 2008 when Mr Cushnahan worked with the Graham family's bookmaking business before their business relationship broke down.
In July a Dáil committee heard Mr Cushnahan was set to pocket £5m in an abandoned bid by US firm Pimco to purchase the northern loan book.
