Lawyer Michael Avenatti was arrested on federal charges of extortion, wire fraud and bank fraud on Monday.
Monday's arrest came after Avenatti reportedly tried to extort Nike for $20 million, according to CBS News. The U.S. attorney for the Southern District of New York announced the extortion charges, while the U.S. attorney in Los Angeles charged Avenatti with bank and wire fraud.
Avenatti tweeted on Monday that he was holding a press conference on Tuesday to "disclose a major high school/college basketball scandal perpetrated by [Nike] that we have uncovered." He was arrested about an hour after sending the tweet.
