By Jim Forsyth SAN ANTONIO (Reuters) - A former financial adviser for ex-NBA star Tim Duncan, whom the San Antonio Spurs legend has accused of bilking him out of millions of dollars, has been indicted on federal fraud charges, court papers unsealed on Friday showed. Charles Banks, 49 and head of Colorado-based Gameday Entertainment, was arrested of federal wire fraud charges on suspicion of defrauding an unnamed San Antonio investor out of millions of dollars, U.S. prosecutors in Texas said. The investor was former San Antonio Spurs star Duncan and the amount misappropriated through a series of financial schemes totaled $7.5 million to $13 million, an attorney for Duncan said in an interview.
