More than a year and a half after Iceland's major banks failed, all but sinking the country's economy, police have begun rounding up a number of top bankers while other former executives and owners face a $US2 billion ($2.24 billion) lawsuit. Since Iceland's three largest banks - Kaupthing, Landsbanki and Glitnir - collapsed in late 2008, their former executives and owners have largely been living untroubled lives abroad. But the publication last month of a parliamentary inquiry into the island nation's profound financial and economic crisis signalled a turning of the tide, laying much of the blame for the downfall on the former bank heads who had taken inappropriate loans from the banks" they worked for. Overnight, the administrators of Glitnir's liquidation announced they had filed a $US2 billion lawsuit in a New York court against former large shareholders and executives for alleged fraud. "I think this lawsuit is without precedence in Iceland," Steinunn Gudbjartsdottir, who chairs Glitnir's so-called winding-up board, told reporters in Reykjavik. The bank also said it was "taking action against its former auditors PricewaterhouseCoopers (PwC) for facilitating and helping to conceal the fraudulent transactions engineered by [its principal shareholder] and his associates, which ultimately led to the bank's collapse in October 2008."
