KNOXVILLE, Iowa (AP) -

A teacher accused of sexually abusing a 15-year-old girl has resigned from his job at a Knoxville high school.

Des Moines television station KCCI reports Troy N. Rider submitted his resignation Monday night as football coach and physical education teacher for Knoxville High School. The resignation is effective April 1.

Rider is charged with third-degree sexual abuse and sexual exploitation by a school teacher. Court records do not list an attorney.

Rider has been on paid leave since he turned himself in to authorities in early March. Police say they received a report about alleged sexual abuse involving a student at Knoxville High School.

Rider's next court hearing is scheduled on April 18.
