Credit Suisse handled billions of dollars in dirty money for decades, an international media investigation based on a massive data leak claimed on Sunday, in the latest setback for Switzerland’s second-largest bank. Reuters reports that the bank held more than $8 billion in accounts of criminals, dictators, and human rights abusers, among others, according to the investigation by a group comprising dozens of media organisations. Credit Suisse rejected the ‘allegations and insinuations’, saying in a statement that many of the issues raised were historical, some dating back more than 70 years.
