An Omaha Public Schools teacher admitted he has made inappropriate contact with several students during his teaching career. 

Gregory Sedlacek, 30, made the admission during his first court appearance after it was reported he had touched a student inappropriately.

Sedlacek, a first-grade teacher at Fontenelle Elementary, was arrested for first-degree sexual assault. 

He was reported earlier this week for a Nov. 20 incident in which he was touching a 7-year-old girl's buttocks while sitting on a slide with her.

Prosecutors say Sedlacek listed other students he had inappropriately touched in his years teaching at the Pine Ridge Reservation and Omaha's Sacred Heart.

Sedlacek is being held without bail.
