NORTH HAVEN, Conn. (AP) The chairman of the North Haven Housing Authority board has been arrested on charges he sexually assaulted a male guest at a party at his home.

The New Haven Register reports that Ralph W. Cook IV was arrested Tuesday and charged with first-degree sexual assault and unlawful restraint.

The 49-year-old Cook is held in lieu of $250,000 bail. He has served as chairman, a voluntary job, at the Housing Authority for four years.

Police said Cook forced the guest to have sex with him at his home in October 2013. Police investigated for a year.

Cook is due to be arraigned Wednesday at state Superior Court in Meriden.

A number listed in Cook's name was not working Wednesday morning and it was not immediately known if he's represented by a lawyer.
