Sam Bankman-Fried, who founded and led FTX until a liquidity crunch forced the Bahamas-based cryptocurrency exchange to declare bankruptcy, was arrested on Monday in The Bahamas after being criminally charged by U.S. prosecutors.

The attorney general's office for The Bahamas said it proceeded with the arrest after receiving formal confirmation of charges against Bankman-Fried, adding that it expects he will be extradited to the United States.

A spokesman for the U.S. Attorney's office in Manhattan confirmed Bankman-Fried had been arrested in The Bahamas but declined to comment on what the charges were.

"Earlier this evening, Bahamian authorities arrested Samuel Bankman-Fried at the request of the U.S. Government, based on a sealed indictment filed by the United States Attorney's Office for the Southern District of New York," United States prosecutor Damian Williams said in a statement. "We expect to move to unseal the indictment in the morning and will have more to say at that time."

Mark Cohen, a lawyer for Bankman-Fried, did not immediately respond to a request for comment.

FTX, which had been among the world's largest cryptocurrency exchanges, filed for bankruptcy protection on Nov. 11 in one of the highest-profile crypto blowups after traders pulled $6 billion from the platform in three days and rival exchange Binance abandoned a rescue deal.

The liquidity crunch came after Bankman-Fried secretly moved $10 billion of FTX customer funds to Alameda, Reuters reported, citing two people familiar with the matter. At least $1 billion in customer funds had vanished, the people said.

Bankman-Fried told Reuters the company did not "secretly transfer" but rather misread its "confusing internal labeling." Asked about the missing funds, he responded: "???"

In a series of interviews and public appearances in late November and December, Bankman-Fried acknowledged risk management failures but sought to distance himself from accusations of fraud, saying he never knowingly commingled customer funds on FTX with funds at his proprietary trading firm, Alameda Research.

"I didn't ever try to commit fraud," Bankman-Fried said in a Nov. 30 interview at the New York Times' Dealbook Summit, adding he doesn't personally think he has any criminal liability.

Bankman-Fried resigned as FTX's chief executive officer the same day as the bankruptcy filing.

The U.S. Attorney's Office in Manhattan, led by veteran securities fraud prosecutor Williams, in mid-November began investigating how FTX handled customer funds, a source with knowledge of the probe told Reuters.

The Securities and Exchange Commission and Commodity Futures Trading Commission also opened probes.

U.S. crypto investors also sued Bankman-Fried, alleging he and a slew of celebrities who promoted FTX engaged in deceptive practices, leaving the investors with $11 billion in damages.

FTX's demise marked the latest turmoil for the cryptocurrency industry this year. The overall crypto market has slumped amid a string of meltdowns that have taken down other key players including Voyager Digital and Celsius Network.
