(Bloomberg) -- Deutsche Bank AG was fined 13.5 million euros ($16 million) by Frankfurt prosecutors over money-laundering violations related to work with Danske Bank A/S.

The bank failed on more than 600 occasions to file timely alerts to authorities about suspicious transactions, Frankfurt prosecutors said in a statement Tuesday. A related criminal probe against bank employees was dropped because no criminal action was found, they said.

The case is linked to a scandal that saw more than $200 billion in suspicious transfers made through Danske Bank’s Estonian unit. The vast majority of the money was also routed through Deutsche Bank, which at the time processed U.S. dollar payments for the Estonian business, people familiar with the matter said last year.

Deutsche Bank said that it had ended its role as Danske Bank Estonia’s so-called correspondence bank in 2015. It also emphasized that prosecutors had dropped the criminal probe.

“With the closure of these proceedings it is clear that there was no evidence of criminal misconduct either on the part of Deutsche Bank or its employees,” Stefan Simon, a member of Deutsche Bank’s management board, said in the statement.
