A social media celebrity, Ramon Abbas, known as 'Ray Hushpuppi' on Instagram, has been charged with running a global scam which allegedly targeted a Premier League club.
The Nigerian national was arrested last month in Dubai following an investigation led by the FBI.
He has been transferred to the US and appeared in court in Chicago.
Dubai police released a dramatic video of Abbas' arrest when a team raided his home while he was asleep.
The 37-year-old is known to post pictures showing his extravagant lifestyle on his social media account, which has 2.4 million followers.
In court documents, the US Department of Justice alleged: "Abbas maintains social media accounts that frequently showed him in designer clothes, wearing expensive watches and posing in or with luxury cars and charter jets.
"The FBI's investigation has revealed that Abbas finances this opulent lifestyle through crime."
He is accused of operating a business email compromise (BEC) scheme, hacking corporate emails, and conspiring to launder money.
"Abbas and others further conspired to launder hundreds of millions of dollars from other fraudulent schemes and computer intrusions, including one scheme to steal £100m (approximately $124m) from an English Premier League soccer club," the Department of Justice said.
The name of the club has not been revealed.
