NEW YORK (AP) — FTX founder Sam Bankman-Fried is returning to New York City for a court hearing Friday that could decide whether the fallen cryptocurrency wiz must go to jail while he awaits trial.

Prosecutors have asked a judge to revoke Bankman-Fried's bail, claiming he tried to harass a key witness in his fraud case. His lawyers insist he shouldn't be jailed for trying to protect his reputation against a barrage of unfavorable news stories.

The 31-year-old has been under house arrest at his parents' home in Palo Alto, California, since his December extradition from the Bahamas on charges that he defrauded investors in his businesses and illegally diverted millions of dollars' worth of cryptocurrency from customers using his FTX exchange.

Bankman-Fried's $250 million bail package severely restricts his internet and phone usage.

Two weeks ago, prosecutors surprised Bankman-Fried's attorneys by demanding his incarceration, saying he violated those rules by giving The New York Times the private writings of Caroline Ellison, his former girlfriend and the ex-CEO of Alameda Research, a cryptocurrency trading hedge fund that was one of his businesses.

Prosecutors maintained he was trying to sully her reputation and influence prospective jurors who might be summoned for his October trial.

Ellison pleaded guilty in December to criminal charges carrying a potential penalty of 110 years in prison. She has agreed to testify against Bankman-Fried as part of a deal that could lead to a more lenient sentence.

Bankman-Fried's lawyers argued he probably failed in a quest to defend his reputation because the article cast Ellison in a sympathetic light. They also said prosecutors exaggerated the role Bankman-Fried had in the article.

They said prosecutors were trying to get their client locked up by offering evidence consisting of "innuendo, speculation, and scant facts."

Since prosecutors made their detention request, U.S. District Judge Lewis A. Kaplan has imposed a gag order barring public comments by people participating in the trial, including Bankman-Fried.

David McCraw, a lawyer for the Times, has written to the judge, noting the First Amendment implications of any blanket gag order, as well as public interest in Ellison and her cryptocurrency trading firm.

Ellison confessed to a central role in a scheme defrauding investors of billions of dollars that went undetected, McGraw said.

"It is not surprising that the public wants to know more about who she is and what she did and that news organizations would seek to provide to the public timely, pertinent, and fairly reported information about her, as The Times did in its story," McGraw said.
