A former basketball coach at a charter high school in Boulder has been arrested for investigation of alleged harassment of a girl he had coached.

Boulder police say 35-year-old Antonio Rodriguez Junior -- who was fired from the Justice High School basketball program in January -- turned himself in to authorities Thursday.

Authorities say a 16-year-old student who was on the team reported in January that Rodriguez had sent her sexually explicit text messages and had made inappropriate comments in front of her and other female students.
