The Lincoln Journal Star says Alex Garden was charged Wednesday with first-degree sexual assault of a child and intentional child abuse.
Police say he sexually assaulted a girl he knew in February. The girl is younger than 12.
Garden has been in the Saline County jail in Wilber since June, when federal prosecutors said he violated the terms of his parole.
In 2016, Garden admitted to possessing child pornography and was sentenced to federal prison. He was put on house arrest late last year, and then put on supervised release months later.
