A Westminster police officer, who was arrested Monday after allegations surfaced that he sexually assaulted a woman, has been charged with the crime.

The 17th Judicial District Attorney’s Office charged Curtis Lee Arganbright, 40, with sexual assault using force to obtain submission and sexual assault of a person in custody by a person in a position of authority.

Few details of the allegation have been made public and an arrest affidavit is under seal, said Sue Lindsay, of the 17th District Attorney’s office.

The alleged sex assault happened at about 1:30 a.m. Aug. 23 in the area of West 144th Avenue and Zuni Street in Broomfield, police said.

The woman brought the allegations to Westminster police, who then contacted Broomfield police. The two departments held a joint news conference Monday evening.

The allegations “sicken my soul” and have “left me numb,” said Westminster Police Chief Tim Carlson.

Arganbright, a former Federal Heights officer who has been with Westminster since December 2013, was arrested on suspicion of multiple felonies: sex assault, sexual assault by a person in position of authority and false imprisonment.

Arganbright was booked at the Broomfield jail and is free on $20,000 bond. His next court appearance is scheduled for 1:30 p.m. Oct. 5.
