The trial of three former officials of Anglo Irish Bank, who are accused of hiding accounts connected to the bank's former chairman Seán FitzPatrick from the Revenue Commissioners, has heard that changes were made to some account details on the bank's core system after the accounts had been closed.

Patrick Peake, the former head of group fraud prevention at the bank is continuing his evidence in the trial of Bernard Daly, Tiernan O'Mahoney and Aoife Maguire.

All three deny the charges against them.

The court also heard that one of the three defendants, Mr O'Mahoney, was given a joint loan of $1.2m with Mr FitzPatrick in 1998 to buy shares in a US company.

Mr Peake began an investigation in April 2010 into allegations that some accounts had been removed from Anglo Irish Bank's core banking system.

He gave evidence that an Isle of Man address had been added to the details of an account belonging to a company called Lock Limited in 2003, roughly two years after the account was closed.

He said there were changes made to the details of a number of accounts in the name of Lock Limited after the accounts had closed.

Mr Peake also gave evidence about accounts in the name of Carnahalla.

The name and address on one of these accounts was changed in 2003.

A second account opened in 1997 and closed in 2000 had details changed in 2004.

The court heard that Anglo Irish Bank loaned $1.2m to Sean FitzPatrick and Tiernan O'Mahoney in 1997 for the purposes of buying shares in a company called Spiros.

The court was told this loan was a bridging loan for just two months pending the draw down of a loan facility from Guinness and Mahon private bank.

The court has also been hearing details of transfers from Sean FitzPatrick's accounts into the accounts of a company called Triumvirate Properties Limited.

Mr Peake told the court that a lodgement of £3,500 punts in 1999 was from Sean FitzPatrick and was recorded as such in a statement printed out in 2003.

However, the court heard Mr FitzPatrick's name was not on a statement Mr Peake gave to gardaí in 2012.

Mr Peake agreed that some time between 2003 and 2012, Mr FitzPatrick's name had been removed from the records.
