A US judge has revoked Sam Bankman-Fried's bail and ordered him to jail due to alleged witness tampering. Bankman-Fried, the founder of FTX, will remain in custody until his criminal trial begins on October 2. The judge's decision was based on evidence that Bankman-Fried had attempted to intimidate a witness, Caroline Ellison, by leaking her private diary entries to the press. This is the latest development in Bankman-Fried's case, which involves multiple charges of wire and securities fraud related to the alleged multibillion-dollar FTX fraud.
