A Portland police officer who lives in Windham has been charged with two counts of misdemeanor assault stemming from a fight early last month in Portland’s Old Port.

Todd Bacon, 30, pleaded not guilty to charges that he assaulted two men on Fore Street at 1:30 a.m. July 2. His lawyer, Michael Cunniff entered the plea last week in Cumberland County District Court, stating that his client acted in self-defense with one of the alleged victims. The contact with the other man was accidental, Cunniff said.

Cumberland County District Attorney Stephanie Anderson did not return calls seeking comment on the case, which is also under intrnal investigation by the Portland Police Department.
