A softball coach has been accused of sexually assaulting a teenage girl.

Ryan Jon Loofboro, 34, has been arrested and charged with aggravated sexual assault of a child and indecency with a child.

Friendswood police said their investigation began in May, after a 13-year-old girl told her parents about the incidents.

Detectives said Loofboro, a real estate agent, had sexual contact with the girl at least twice during the 2012 softball season, once in March and once in April.

Loofboro was arrested during a traffic stop on Thursday. He's being held in the Harris County Jail with bond set at $80,000.

Investigators said if parents have children in the Friendswood Girls Softball Association, they should make sure the child has not had any inappropriate contact with Loofboro.
