The general manager of independent radio station Lightning 100 was arrested over the weekend after a grand jury indicted him on two felony sex charges. Fred Buc, a longtime radio executive and host in Nashville, was charged with one count of sexual exploitation of a minor and a count of displaying sex acts to a minor older than 13. Authorities said he was arrested on Saturday night at his west Nashville residence and has since been released on a $100,000 bond. According to police, Buc allegedly displayed sexually explicit material to an undercover officer posing as a minor in September 2011. Police also discovered material that included a minor engaged in sexual activity on computers used by Buc.
