Wow! Jackpot! At least according to Wikipedia:
Laundering stolen money, Prevezon Holdings, and Sergey P. Poymanov
Sergei Leonidovich Magnitsky accused numerous persons and entities of laundering stolen money in tax fraud in Russia. Owned by Denis Katsyv, Prevezon Holdings, represented by Natalia Vladimirovna Veselnitskaya, paid $6 million to resolve the claim without admitting any crime which subsequently led to all charges being dropped by the Justice Department in the summer of 2017. In United States court, Sergey P. Poymanov sued Sberbank, several of its subsidiaries and executives, and a business rival for $750 million, claiming that a valuable gravel quarry he owned was illegally bankrupted and seized by the bank in a corporate raid in 2012. Sberbank says it took the quarry as collateral after Mr. Poymanov failed to repay a loan. Sberbank is retaining Marc Kasowitz for this court case. Poymanov was subsequently arrested by Russian police who then subjected him to harsh pretrial detention at a notoriously rough Moscow jail, Matrosskaya Tishina, which is the same jail where Magnitsky died.
