Police walk in front of Deutsche Bank headquarters in Frankfurt, Germany, on November 29, 2018. The papers were from the Panamanian law firm Massack Fonseca, reported to be one of the world's biggest creators of shell companies.
This investigation is separate to another Panama Papers probe which also involves Deutsche Bank.
Niesen said the analysis of the Panama Papers and other documents "gave rise to suspicion that Deutsche Bank was helping clients set up so-called offshore companies in tax havens and the proceeds of crimes were transferred there from Deutsche Bank accounts" without the bank reporting it.
In 2016 alone, more than 900 customers are alleged to have transferred €311m to one such company in the British Virgin Islands, a spokeswoman said.
Deutsche Bank (DB), which the publication notes has spent $18 billion on "fines and legal disputes" over the past ten years, reportedly has multiple links to the Panama Papers scandal.
