A lawsuit has been filed alleging that a man who is interim principal at King Street Primary School in Danbury sexually abused a boy over a seven-year period in the late 90s.  37-year old Marc Poliquin denied the allegations and says he will fight the suit in Waterbury Superior Court.  The Danbury Board of Ed and Superintendent are looking into the matter, but did not comment further.  The complaint alleges Poliquin started abusing a boy in 1996, when he was 15 and the boy was 10.  The complaint says the alleged abuse ended in 2003, when Poliquin was 22.  The plaintiff’s attorney told the Hartford Courant that her client wasn’t going to come forward at all, but when he learned Poliquin was named principal, he decided he had to speak out.
