The state prosecutor?s office is heading up a sexual misconduct investigation of a Norwalk police officer, authorities said Monday.

?We wanted that to be the case because we wanted to avoid any appearance of impropriety,? Chief Harry Rilling said of the case. Rilling also said he didn?t want to jump to any conclusions about Lt. Thomas Cummings.

Cummings, 46, is accused of improper sexual conduct with a 15-year-old Weston boy. Police said he met the teen on the Internet. Investigators searched the lieutenant?s home and seized his computer more than a week ago.

Rilling stressed that the incident should not be a reflection on the police force. ?We hold police officers to the highest possible standards and anything less than that is unacceptable.?

Cummings hasn?t been charged with any crime.
