Lawyers have for the first time been able to see some of the stolen Credit Suisse data that was controversially acquired earlier this year by some German states, according to a media report.

The stolen disk has been said to contain data with the names of 1,100 Credit Suisse clients in Germany with Swiss accounts.

German lawyers have told Bilanz, a Swiss business magazine, that tax investigators provide clients suspected of tax evasion with a copy of two small lines from the disk, containing the clients’ account numbers, the names, date of birth, amount of assets in the Swiss account and the opening date of the account. This appears to be enough for a criminal investigation to take place.

This report therefore confirms that the stolen data is indeed from Credit Suisse, something that has been expected. Bilanz adds that the data is likely to contain information of clients from Credit Suisse branches in Zurich, Basel, St Moritz and Geneva.

Credit Suisse referred to its financial report for the first quarter of this year, in which the Swiss banking giant said it had filed criminal charges against the individuals who committed the data theft. The individuals remain unidentified.
