Sam Bankman-Fried, founder of the collapsed cryptocurrency exchange FTX, has been arrested in The Bahamas, the country’s attorney general has said.
He is scheduled to appear on Tuesday in a magistrates’ court in the Caribbean country’s capital, Nassau.
Police said Mr Bankman-Fried, 30, was arrested for “financial offences” against laws in the US and The Bahamas.
Last month FTX filed for bankruptcy in the US, leaving many users unable to withdraw their funds.
According to a court filing last month, FTX owed its 50 largest creditors almost $3.1bn (£2.5bn).
Among the most serious allegations against Mr Bankman-Fried is that he used billions of dollars of customer funds to prop up his investment trading company, Alameda.
It is unclear how much people who have funds in the exchange will get back at the end of bankruptcy proceedings – though many experts have warned it may be a small fraction of what they deposited.
The FTX exchange allowed customers to trade normal money for cryptocurrencies like Bitcoin.
Cryptocurrencies are not currencies in the traditional sense, but are stored online and act more like investment vehicles or securities – often with a high degree of volatility.
Their anonymity means they have been favoured for criminal activities such as drug dealing and ransomware attacks, but their supporters say there is huge potential for innovation – and independence from governments.
Mr Bankman-Fried was once viewed as a young version of legendary US investor Warren Buffett, and as recently as late October had a net worth estimated at more than $15bn.
He had become well known in Washington DC as a political donor, mostly to Democratic politicians or groups, supposedly supporting pandemic prevention and improved crypto regulation.
Mr Bankman-Fried will be held in custody “pursuant of our nation’s Extradition Act,” the Attorney General of the Bahamas said in a statement.
“Earlier this evening, Bahamian authorities arrested Samuel Bankman-Fried at the request of the US Government, based on a sealed indictment filed by the SDNY [Southern District of New York]. We expect to move to unseal the indictment in the morning and will have more to say at that time,” the US Attorney’s office in Manhattan said in a tweet.
Wall Street regulators also said that they would be taking action against Mr Bankman-Fried.
“We commend our law enforcement partners for working to secure the arrest of Mr Sam Bankman-Fried in the Bahamas on federal criminal charges,” US Securities and Exchange Commission (SEC) official Gurbir Grewal said in a statement.
“The Securities and Exchange Commission has separately authorised charges relating to Mr. Bankman-Fried’s violations of our securities laws, which will be filed publicly tomorrow in the Southern District of New York,” he added.
Mr Bankman-Fried had been due to testify about the collapse of FTX before the US Congress on Tuesday.
However, he will now be unable to testify, according to Congresswoman Maxine Waters, who said in a statement that she was surprised to hear that he had been arrested.
Mr Bankman-Fried’s lawyer did not immediately reply to a BBC request for comment.
