Former Anglo Irish Bank CEO David Drumm has hired two of America's top white-collar crime lawyers to join his legal team fighting an extradition request from Ireland.

Mr Drumm was arrested earlier this month and has been held in custody in a detention facility in Massachusetts for almost two weeks.

Ireland has asked the US authorities to return him to face 33 charges in the Irish courts relating to transactions that occurred while he was CEO of Anglo Irish Bank. 

His bail hearing was due to take place last Friday, but has been postponed until Monday 26 October, following a request from his lawyer for more time to gather evidence from the case, including from Ireland.

Today Mr Drumm's lawyer Tracy Miner has filed legal paperwork to be joined by two New-York based lawyers - Edward McNally and Daniel Fetterman.

Mr McNally is a former US Attorney and following the 11 September 2001 attacks, he was appointed by President George W Bush as the country's first General Counsel for Homeland Security and counter-terrorism.

Mr McNally has also served as an advisor to three US Presidents and seven attorneys general.

Daniel Fetterman is a former assistant US Attorney who has lectured at the University of Washington and Lee University and has written a book on white-collar crime, which is used in law school courses and Harvard and Yale.

Both Mr Fetterman and Mr McNally work at the Kasowitz, Benson, Torres and Friedman firm in New York city.

Judge Donald Cabell has now issued orders granting permission to Mr Fetterman and Mr McNally to join Mr Drumm's legal defence team in Massachusetts.

The two lawyers needed permission from the judge because they are licensed to practice in another state - New York.
