TWIN FALLS -- Twin Falls deputies arrested two women this week during a prostitution sting.

Myeong Sook Mickley, 46, and Sun Do Chong, 57, were charged in 5th District Court Friday after prosecutors said they offered illegal sexual services at the southern Idaho town's Osaka Massage and Spa.

The women's cases are the first alleged prostitution incidents in two years in Twin Falls.

Authorities said the women led undercover male deputies by the hand into rooms and offered to perform sexual acts for money.

During the sting operation, police say they counted nine men enter Osaka on Oct. 23 and then leave 25 to 30 minutes later, court records show. Prostitution customers haven't been charged.

Mickley and Chong allegedly told police that an Asian woman in New York instructed them to come to Twin Falls.
