German authorities searched Deutsche Bank headquarters in Frankfurt. The operation was part of a probe into suspected tax evasion, according to one source.
Another source reported that the investigation concerns fraudulent tax claims made by Deutsche Bank's subsidiary Postbank between 2008 and 2010.
The investigation targets 10 former senior managers, according to a source.
There are conflicting accounts regarding who conducted the search. One source stated that German tax investigators raided the headquarters, while another said prosecutors carried out the search.
