OMAHA, Neb. -- An Offutt Air Force Base security officer, is now facing charges and has a preliminary hearing set for later this summer. 

27-year-old John Channels was allegedly arrested in May for a sexual relationship with a girl starting when she was about 12-years-old. 

Channels was charged with three felonies: first-degree sexual assault of a child, visual depiction of sexually explicit conduct of a child, and attempted intentional child abuse. 

Court documents show the victim said she knew him since she was ten when he taught her TaeKwonDo. 

A preliminary hearing has been scheduled for July 11th.
