Sam Bankman-Fried, co-founder of FTX, has returned to the Metropolitan Detention Center in Brooklyn, New York after being transferred to prisons in Oklahoma and Pennsylvania last month. The transfer was in accordance with Judge Lewis Kaplan's request to facilitate contact with his appeal lawyers. Bankman-Fried was sentenced to 25 years in prison last year for multiple fraud charges related to the collapse of the cryptocurrency exchange FTX. Another FTX official, Ryan Salame, was sentenced to 7 and a half years in prison last week.
