CRANBERRY TWP — A man who police say tried entering the room of a woman arrested on prostitution charges during an undercover operation has now been charged.

Nhiem T. Nguyen, 54, of Cranberry Township, was charged with patronizing a prostitute, a third-degree misdemeanor.

According to Cranberry Detective Justin Hewitt’s affidavit, Nguyen arranged a meeting with the woman after seeing an advertisement on a website that promotes prostitution. That same website led police to the same woman, according to the affidavit.

Nguyen entered the Quality Inn in Cranberry Township on Oct. 24, the affidavit states, and tried walking past an undercover officer and FBI agent to enter the same room where a woman was arrested earlier on prostitution charges.

Upon questioning, Nguyen agreed to let officers look at his cell phone, where, police say, they saw text messages arranging payment in exchange for sexual intercourse.

Though police questioned him on Oct. 24, charges were not filed until Oct. 30, after the arrest of a second woman in Cranberry on prostitution charges.

Court documents indicate Nguyen is not in custody and do not show if he has an attorney. A preliminary hearing is scheduled in December.
