(AP) — An Oklahoma doctor is charged with using a teenage Missouri boy to produce child pornography.

The U.S. attorney’s office says Shelby Coleman was arrested over the weekend after going to a Springfield hotel and texting instructions for the 16-year-old to come to his room. The 36-year-old Tulsa Women’s Health Clinic doctor was charged Monday in federal court and is being held in the Greene County Jail. No attorney is listed for him in online court records.

An affidavit says Coleman and the Laclede County teen sent one another sexually explicit text messages and images. The teen’s father contacted the Missouri State Highway Patrol after discovering the messages, and a state trooper used the teen’s phone to set up the meeting.
