Ryan Jon Loofboro, 34, is charged with aggravated sexual assault and indecency with a child. He was arrested Thursday afternoon in Dickinson.
According to Friendswood police, the charges stem from a report taken in early May that Loofboro had sexual contact with the girl during the 2012 softball season. A six-week investigation followed, and the Galveston County DA's office accepted charges.
After his arrest, Loofboro was taken to the Friendswood city jail. His bail was set at $40,000 on each charge.
Police are encouraging parents of children in the Friendswood softball league to speak to their kids to determine whether or not there are other victims.
