FRANKFURT: Prosecutors, federal police and other officials searched Deutsche Bank’s headquarters in Frankfurt on Friday in a move Germany’s largest lender said was linked to suspicions of money laundering it had reported to the authorities.

Under Chief Executive Christian Sewing, Deutsche Bank has been trying to repair its reputation after a series of embarrassing and costly regulatory failings.

In a statement, Deutsche Bank said the search involved suspicious transactions it had itself passed on to authorities and that it was cooperating fully.

Prosecutors said they had a search warrant but declined to elaborate. They said representatives of financial regulator BaFin were also taking part.

BaFin and federal police declined to comment.

The bank’s shares fell more than 3% following news of the search and were down 2.7% in early afternoon in Frankfurt.

Problems with money laundering have landed the bank in hot water in the past. The US Department of Justice has been investigating it for years, for example, over trades that authorities said were used to launder $10 billion out of Russia, which has led to the German bank being fined nearly $700 million.

In 2018, BaFin took the unusual step of installing KPMG as a special monitor at Deutsche to oversee progress on money laundering controls.

Last year, BaFin ordered Deutsche to enact further safeguards to prevent money laundering and the regulator widened the auditor’s mandate. Deutsche has said it has beefed up resources to combat money laundering.
