Mayor Mark Boughton of Danbury has fired a police officer over his treatment of an immigrant during a traffic stop. Boughton fired Officer Chris Belair after reviewing an audio tape, video, and other materials related to the stop in March. Boughton wrote that while the driver was cooperative, the officer told him to leave the country and threatened to beat him. Boughton also wrote that he suspected the officer was physically aggressive toward the operator, but said the videos and pictures were not clear due to weather conditions.
