Deutsche Bank shares fell sharply in early European trading after the Frankfurt public prosecutor's office confirmed that investigators raided one of the bank's branches on Tuesday.
The search took place at the lender's prominent Taunusanlage location in Frankfurt's financial district, according to reports from Handelsblatt.
Prosecutors executed a search warrant issued by the local district court in June.
While authorities have not disclosed the specific subject matter of the investigation, the confirmation of the raid has triggered immediate selling pressure on the stock.
The move underscores the persistent regulatory risks facing major German lenders, even as the sector attempts to stabilize after years of compliance-related headwinds.
The raid comes amid a broader wave of law enforcement activity in Frankfurt.
