DES MOINES (AP) -- A Des Moines dormitory director has pleaded not guilty to a federal child pornography charge.
Twenty-seven-year-old Kent Oman was indicted last week on a single count of producing child pornography.
Federal authorities allege Oman produced nude recordings of a teen he mentored through Big Brothers Big Sisters from his dorm at the AIB College of Business.
Oman, who is being held in Polk County Jail, entered his plea Thursday. His attorney says he will appeal Oman's detention.
Oman is set to stand trial May 31.
Authorities said that Oman, a Cherokee native, will remain in custody until a grand jury hears his child pornography case.
Prosecutors claim Oman used a hidden camera, planted in his bathroom, to tape a teenaged boy from 2008 to 2010. A special agent also testified that investigators found video of a young woman in evidence seized from Oman's room at Felton Hall.
