German prosecutors searched offices at Deutsche Bank's headquarters in Frankfurt on Wednesday as part of an investigation into alleged fraudulent tax transactions linked to the lender's Postbank unit years earlier.
The bank confirmed that Duesseldorf prosecutors were at its office in the city, and that the probe related to transactions at its Postbank division between 2008 and 2010.
"Deutsche Bank is being searched as a third party in this matter and we are cooperating fully," Deutsche Bank said, declining to comment further.
Duesseldorf prosecutors did not immediately respond to a request for comment.
Probe relates to 'cum-cum' trades
