FTX co-founder Sam Bankman-Fried (SBF) has been on house arrest in California since December while awaiting trial on fraud and money laundering charges over the crypto exchange’s collapse, but today he was sent to jail, as first reported by Inner City Press.

Judge Lewis A. Kaplan ordered the former billionaire remanded after prosecutors pushed to have his bail revoked, citing violations that included Bankman-Fried’s admitted usage of VPN software that he said was to watch an NFL game and the judge’s view that he had attempted to tamper with witnesses “at least twice.”

Docket entry from Friday’s Bond Revocation Hearing:

The witness tampering covered Bankman-Fried sharing documents used in a New York Times article reporting on Google Docs diary entries written by Caroline Ellison, the former co-CEO of Alameda Research and SBF’s ex, who has already pleaded guilty and is cooperating as a witness against him. The other incident covered Bankman-Fried’s attempts in January to contact FTX general counsel Ryne Miller over email and the encrypted messaging platform Signal.
