AIB continues Rusnak counterparties enquiry

"There is an investigation ongoing," said a spokesperson at AIB in Dublin. This will help the bank decide if it has a legal case against other parties, he said, but noted: "It’s still early days."

AIB has not named Citi as its potential target, but the US bank is the most likely object of an enquiry into Rusnak’s activities because it suspended two sales dealers last March following its own internal investigation into the affair. New York trader Richard Marra and Singapore-based Joseph Craven
