Fontenelle Elementary Principal Eric Nelson made his first court appearance Tuesday accused of felony child abuse.
He has posted bail and faces a preliminary hearing in March.
Nelson was arrested for failing to report information in an alleged abuse case involving a teacher.
Teacher Greg Sedlacek has been arrested for child sexual assault. Authorities became aware of that case when teachers at the school saw Sedlacek acting inappropriately with a 7-year-old student during recess.
Sedlacek faces six counts of First Degree Assault and one count of Third Degree Assault.
Prosecutors said witnesses told Nelson on November 18th about Sedlacek's alleged activity.
Douglas County Attorney Don Kleine said, "He didn't report it."
Principal Nelson was placed on administrative leave.
