Nassau, bahamas>> A federal prosecutor says two associates of Sam Bankman-Fried have pleaded guilty to criminal charges related to the collapse of the cryptocurrency exchange FTX.

Carolyn Ellison, the former CEO of Alameda Research, a trading firm started by Bankman-Fried, and Gary Wang, who co-founded FTX along with Bankman-Fried, pleaded guilty to charges “related to their roles in the fraud that contributed to FTX’s collapse,” U.S. Attorney Damian Williams said.

In agreements signed with prosecutors on Dec. 19, Ellison and Wang agreed to plead guilty to charges including wire fraud, securities fraud and commodities fraud.

The guilty pleas were announced as Bankman-Fried was being flown to the U.S. from the Bahamas by U.S. law enforcement to answer to charges tied to his role in FTX’s failure.

Bankman-Fried was being extradited to the United States, where he faces criminal charges related to the collapse of the cryptocurrency exchange.

Reporters on the scene witnessed Bankman-Fried leaving a Magistrate Court in Nassau in a dark SUV earlier Wednesday. The vehicle was later seen arriving at a private airfield by Nassau’s airport.

He was due to land in New York.
