Due to the suspicion of tax fraud, raids have been carried out in Credit Suisse branches in London, Paris and Amsterdam.
A media report had previously referred to raids in several countries, involving some 55,000 suspicious accounts.
According to the Reuters news agency, the Dutch authorities said Friday that the background for the raids was a clue to secret bank accounts at a Swiss bank. Several holders of 3800 accounts with connections to the Netherlands were affected.
Confiscated assets
In the Netherlands, Great Britain, Germany, France and Australia, coordinated searches began on Thursday. Paintings, gold bars, cash and other assets in millions were confiscated, an official spokeswoman said.
Credit Suisse informed on Friday morning, in response to the media itself, "visits to local authorities" in London, Paris and Amsterdam. "We are working together with the authorities," says the financial institute.
Since 2013, Credit Suisse has been applying the withholding tax agreement between Switzerland and Great Britain, it says. The voluntary tax-exemption programs of the Netherlands and France had also been implemented and relationships with non-tax-compliant customers had been terminated.
Credit Suisse has also implemented the automatic information exchange, which will enter into force in April 2017, for its European locations. Credit Suisse continues to pursue a strategy of complete tax compliance, the Institute stressed.
