A congressional candidate plans to file an excessive force complaint against Westport's police department following his arrest last month.  TJ Elgin made his first appearance in court Monday on charges of breach of peace and interfering with an officer.  The GOP 4th District candidate was arrested at his home December 21st when a neighbor reported a man yelling and kicking at the door.  The 30-year old says it was a misunderstanding--he forgot his key and was trying to wake his grandmother, who also lives in the home.  Elgin did not enter a plea and the case was continued until next month.  He thinks it's related to his announcement days earlier that he was running for office.
