MARSHALLTOWN, Ia. — A Marshalltown school board member who resigned his post as a prosecutor has pleaded not guilty to trespassing and theft charges.

Authorities say a co-worker accused Ben Stansberry of stealing underwear from her home. He was arrested Monday and released. The Marshalltown Times-Republican reports that the two pleas were entered Tuesday. A trial date hasn't been set.

Marshalltown Police Chief Mike Tupper says Stansberry's co-worker reported the underwear missing Aug. 22, after Stansberry stopped by her Marshalltown home. Tupper stressed that the woman and Stansberry only worked together and had no personal relationship.

Stansberry was elected to the Marshalltown school board in November.
