OMAHA, Neb. (AP) — A suburban Omaha assistant high school principal is facing sex assault charges, accused of having a sexual relationship with a 15-year-old student.

Douglas County Jail records show 45-year-old Matthew Fedde remained in custody Friday. He’s been placed on administrative leave from his job at Millard South High School. He’s been a district employee since 2012.

Omaha police say the girl’s parents contacted authorities after reading her journal.
