Controversial lawyer Michael Avenatti was indicted on charges of trying to extort athletic shoe giant Nike out of tens of millions of dollars by threatening to go public with embarassing information about the company, according to federal court documents unsealed Wednesday in New York.

The indictment, which Avenatti had said Tuesday was imminent, was expected, as he had already been arrested on a criminal complaint that contained similar allegations of a brazen shakedown effort of Nike by hyper-aggressive attorney in March.
