Sam Bankman-Fried, the notorious former CEO of crypto exchange FTX, has been arrested in the Bahamas, the office of the attorney general of The Bahamas said on Monday night.

The arrest was made at the request of the U.S. government, based on a sealed indictment filed by the Southern District of New York, U.S. Attorney Damian Williams said in a tweet also on Monday night.

Williams expects to unseal the indictment on Tuesday morning, and he "will have more to say at the time."

Meanwhile, the Securities and Exchange Commission will file its own charges in the Southern District of New York "relating to Mr. Bankman Fried's violations of our securities laws," its head of enforcement, Gurbir Grewal, said in an email.

The Bahamian attorney general said police made the arrest after officials received "formal notification from the United States that it... has filed criminal charges against" Bankman-Fried, and they learned that the U.S. is "likely to request his extradition."

The office "intends to process" an extradition request "promptly," when it is made.

In a statement, the prime minister of the Bahamas stressed the country is cooperating with law enforcement and regulators in the United States, but its own "regulatory and criminal investigations into the collapse of FTX continue."

Just one month ago, FTX, a $32 billion behemoth in virtual currencies, filed for bankruptcy after suspicions rose that it was insolvent and also moving money around illegally.

Bankman-Fried resigned hours before the bankruptcy filing and has spent the last month on a charm campaign, painting himself as a guy who let things slide and didn't intentionally commit fraud in a variety of media interviews and even on Twitter Spaces.

He was slated to testify virtually from The Bahamas before a congressional committee on Tuesday.

As of late Monday night, the committee still had a notice of the hearing posted that listed Bankman-Fried as a witness and also included the written testimony of the hearing's other witness, FTX's CEO John Ray.

Bankman-Fried has denied that he has avoided coming to the United States over the last month for fear of being arrested. [Copyright 2022 NPR]
