Federal prosecutors in Manhattan said on Friday that the disgraced cryptocurrency executive Sam Bankman-Fried had tried to contact a potential witness in his criminal case, and they asked a judge to impose new bail conditions limiting his ability to communicate with former colleagues.
In a court filing, the U.S. attorney’s office for the Southern District of New York said Mr. Bankman-Fried sent messages over email and the encrypted messaging app Signal this month to the general counsel of the U.S. arm of FTX, the cryptocurrency exchange he founded. Mr. Bankman-Fried, 30, has been charged with fraud, money laundering and campaign finance violations linked to the implosion of FTX last year.
