The former CEO of failed crypto firm FTX Sam Bankman-Fried has been arrested in the Bahamas at the request of the U.S. government, the U.S. attorney’s office in New York said Monday.

Bankman-Fried is under criminal investigation by U.S. and Bahamian authorities following the collapse last month of FTX. The firm filed for bankruptcy on Nov. 11, when it ran out of money after the cryptocurrency equivalent of a bank run.
