Some 3,000 Belgians are believed to have deposited over 5.5 billion euros with HSBC Switzerland. On Sunday the International Consortium of Investigative Journalists published secret bank documents believed to show that HSBC helped wealthy customers to evade taxes.
Rym Kechiche of the Brussels public prosecutor's office: "Detectives travelled to Switzerland two months ago. Two months on we are still waiting for answers. We have asked HSBC to volunteer documents. If the Swiss authorities and the bank fail to co-operate sufficiently then the examining magistrate will consider issuing an international arrest warrant."
