Sanctioned Russian-Uzbek billionaire Alisher Usmanov has filed a lawsuit against UBS Europe SE, a German unit of UBS Group AG, in Frankfurt. Usmanov claims that the bank's anti-money laundering reports, which he describes as 'more than a dozen absurd and unsubstantiated,' triggered a politically motivated investigation against him in Germany. His lawyer says these reports led to an illegal criminal investigation. Usmanov is seeking redress for what he considers to be unfounded accusations that have resulted in significant legal and reputational consequences. The reports were allegedly sent by UBS.
