The parents of FTX founder Sam Bankman-Fried are being sued for money they allegedly received improperly from the crypto firm ahead of its collapse.

In a filing, managers at the bankrupt firm accuse the couple of holding millions of “fraudulently transferred” dollars and of turning a blind eye to misconduct at the company.

The action was filed on behalf of those owed money after the firm’s failure.

The fall of the company led to the arrest of Mr. Bankman-Fried last year.

US prosecutors have accused the former billionaire, once dubbed the “King of Crypto”, of illegally transferring millions from the exchange to plug losses at his trading firm, make political donations, and buy property.

He has denied the charges and is in jail, awaiting trial next month.
