"My conclusion is there is probable cause to believe the defendant tried to tamper with witnesses at least twice," said Judge Kaplan during his ruling. Judge Lewis Kaplan denied Bankman-Fried's request for delayed detention pending an appeal. Sam Bankman-Fried will head to jail on Friday after a judge sided with a request by federal prosecutors to revoke the FTX founder's bail over alleged witness tampering. Judge Kaplan previously issued a direct and stern warning to Bankman-Fried in July over his conversations with the media. It is an argument that proved sufficient to convince Judge Kaplan to send Bankman-Fried to jail ahead of his trial.
