BISMARCK, N.D. (AP) - A Wisconsin man accused of bringing females to North Dakota's oil patch and forcing them into prostitution has pleaded not guilty in federal court.
31-year-old Levell Durr pleaded not guilty to coercion and enticement.
Authorities allege that he used drugs and physical violence to keep the females compliant and at one point kept a girl in a dog kennel for days for breaking one of his rules.
Federal Magistrate Judge Charles Miller set Durr's trial for Sept. 16.
