Federal prosecutors unveiled fraud and bribery indictments on Tuesday against NCAA coaches and representatives from a major sportswear company that were the product of a two-year investigation that the U.S. attorney in Manhattan said exposed the “dark underbelly” of college basketball.

A group of 10 defendants, including four NCAA Division I men's basketball coaches and a high-level Adidas executive were arrested and charged with crimes in relation to two schemes.

In one scheme outlined by prosecutors, financial advisers and business managers allegedly paid bribes to coaches, who in exchange would agree to influence their players to retain the services of the advisers when the players move up to the NBA.
