A 28-year-old Rossville wrestler is facing an aggravated statutory rape charge.
Joshua Francis Carter of 12711 Old Dayton Pike was arrested Tuesday.
He is also charged with sexual exploitation of a minor and sale, loan or exhibition of obscene materials to minors.
County Detective Ed Merritt said he met last Wednesday with an underage girl who said Carter had digitally penetrated her at her home on March 5.
He said the girl and Carter discussed the incident in detail on Facebook.
Detective Merritt said Carter encouraged the girl to take nude photos of herself and told her which app to use to transmit the images. He said the app was "made for sexting.
He said Carter received one of the digital images and made a comment about it.
The detective said after Carter received several of the nude photos of the girl, he sent her one of his penis.
Carter, whose bond was set at $45,000, is due to appear before General Sessions Court Judge Gary Starnes on April 8.
