DETROIT (AP) — A Pittsburgh-area official accused of obstructing police at a Detroit hotel has pleaded no contest to disturbing the peace and was placed on probation. The charge is a misdemeanor. Prosecutors say the case could be dismissed if Chelsa Wagner completes the six-month probation without any problems. Wagner is a Democrat and the elected controller in Allegheny County. She was accused of interfering with police as officers tried to remove her husband from the Westin Book Cadillac hotel last March. Hotel staff had called 911 to report that Mosley was unruly during a dispute over registration and a room key.
