A Newtown man camping on an office building's property in Bethel has been charged with criminal trespass.  Bethel Police responded to 24 Stony Hill Road last week on a report of a man at the rear of the building, who had previously been told not to return to the property.  William Garrison Jacobs Jr. was issued a misdemeanor summons.  He was released on a written promise to appear in court on Tuesday.
