The former CEO of FTX crypto exchange is being accused of using customer funds for personal gain, such as buying luxury real estate, making political contributions, and trading at another company named Alameda.
Two high-level software developers at FTX raised concerns about the missing funds, but their names have not been revealed.
However, Gary Wang and Nishad Singh, who helped found FTX with the CEO, have been named in public charging documents.
Both Wang and Alameda CEO Caroline Ellison have pleaded guilty to fraud, while Singh has not been charged.
The U.S authorities have warned that the CEO is a flight risk and may try to destroy evidence if not apprehended.
