HSBC’s offices in Geneva are raided by prosecutors investigating the scandal over the banks past actions in helping overseas clients avoid taxes.
Geneva’s public prosecutor searched the premises on Wednesday and said it had opened a criminal inquiry into allegations of aggravated money laundering.
“We are looking for everything and anything we can find – documents and files,” a spokesperson for the prosecutor said.
The decision to investigate the bank over allegations of “aggravated money laundering” was taken this week, he added.
The statement said the scope of the investigation would affect individuals who are suspected of having committed or participated in money laundering.

The bank has said in an earlier statement that it would co-operate with all relevant authorities. HSBC declined to comment about the raid.

The bank has said compliance and controls at its Swiss private bank in the period up to 2007 fell short of requirements. But it said the business had been transformed in recent years, adding that many people alleged to have been customers had long since left, and that some never werer clients at the bank.
The disclosures have sparked a political row in Britain over practices at HSBC and whether the UK tax authorities have done enough to pursue possible wrongdoers.
