An Oireachtas Committee is planning to question AIB managing director designate Colm Doherty about the role of his capital markets division in the period before the rogue trader John Rusnak was detected in 2002 committing a €691m fraud.

TDs from the Regulatory Affairs Committee, led by Fianna Fáil's Michael Moynihan and Fergus O'Dowd of Fine Gael, plan to question Doherty at a hearing after receiving information understood to involve his capital markets division.

Moynihan, the chair of the Oireachtas committee, told the Sunday Tribune he had personally passed the information onto minister for finance Brian Lenihan.

It is understood the information involves the activities of an unnamed rogue trader at the AIB New York branch of the capital markets division up to a year before the detection of John Rusnak at the bank's Allfirst unit in Baltimore. Rusnak lost €691m in unauthorised trading before his detection in February 2002.

"I passed the new information onto the minister for finance," Moynihan said.

According to court documents in New York and legal sources in the US and Ireland, Bank of America, which is defending a lawsuit against AIB, is investigating whether public knowledge of an alleged AIB rogue trader in New York would have led to the earlier detection of Rusnak in Baltimore.

AIB is suing Bank of America and Citibank for $480m alleging the banks in their dealings with Rusnak should have known that his trades were unauthorised.

It is understood the new information given to the Regulatory Affairs committee also involves the controversial share trades transacted by Goodbody Stockbrokers, part of capital markets division, in 2000 and 2001 through front companies based in the Caribbean and the south Pacific.

Moynihan's committee has already heard the evidence of what TDs and senators referred to as "the highly credible" testimony of the AIB former chief auditor Eugene McErlean, who was the bank's most senior internal policeman up to 2002.

At the hearing, McErlean received a public apology from AIB's outgoing chief executive Eugene Sheehy about the way the bank had treated its former chief auditor.

An AIB spokeswoman said that the bank had not received an invitation from the Oireachtas Regulatory Affairs Committee. "We haven't had any invitation. When we receive it we will reply to it," a spokeswoman said.

A spokesman for the Department of Finance said it had no comment to make on information that may have been passed onto the minister for finance.

A spokeswoman for Bank of America said it would not comment on its defence case against AIB. "That's not something we'd comment on," she said.

The Sunday Tribune in August reported that about 45 expert witnesses, current and former employees of AIB, Citibank, and Bank of America, including former advisers, have been subpoenaed or have voluntarily agreed to give evidence in the upcoming trial in New York.
