The former chief executive of Anglo Irish Bank is due in federal court in Boston on Tuesday for an extradition hearing as Irish authorities reportedly are preparing to charge him for his role in the collapse of that bank. The executive, David Drumm, was arrested on Saturday in a suburb of Boston, where he had been living since the bank was nationalized in early 2009, and has been in custody since awaiting Tuesday’s hearing, according to a spokeswoman for the U.S. Attorney’s Office in Boston.
