(AP) — A federal jury has acquitted a former northeast Kansas police detective of threatening other officers in his department, including the chief.  The jury on Thursday found John Hudson not guilty on all four counts against him.

Hudson served in the Kansas City, Kan., Police Department for 15 years before retiring two years ago.

Prosecutors said he was upset about Chief Rick Armstrong’s support of a federal sting operation aimed at members of a special unit suspected of stealing items from homes during raids.

Hudson was charged after a former girlfriend told authorities he considered Armstrong and other top officers “rats.” The girlfriend also claimed Hudson made threatening remarks against the officers.

Three members of the special unit were sentenced last year for stealing electronics from homes.
