American entrepreneur Sam Bankman-Fried was sent to jail on Friday after a judge revoked his bail for witness tampering and VPN use.

Bankman-Fried, the founder of the collapsed cryptocurrency exchange FTX, pled not guilty in connection to the alleged multibillion-dollar FTX fraud. He has been accused of stealing billions in customer funds to plug losses at his hedge fund Alameda Research. 

The 31-year-old was taken into custody in December 2022. He has since been out on a $250 million bail package which requires him to stay under house arrest at his parents’ home in Palo Alto, California.

Prosecutors requested that his bail be revoked, alleging that the entrepreneur was trying to influence witnesses in the case.

On Thursday, US District Court Judge Lewis  A. Kaplan said the accused reached out twice to witnesses and sent him to custody directly from a court hearing in New York. His criminal trial is due to begin on October 2.
