BOZEMAN, Mont. -

Three women arrested at Belgrade massage parlors are charged with promoting prostitution.

Justice of the Peace Bryan Adams set bail at $50,000 each Tuesday for 51-year-old Jihong Yu of Belgrade, 52-year-old Yu-Sun Gasperi of Auburn, Wash., and 70-year-old Ok Nan Tenette of Berkeley, Calif.

Court records say a confidential informant told police he had been propositioned for sex at the VIP Spa. Police sent the informant to the spa on Monday wearing a recording device. He said Tenette offered to have sex with him for $120. Police arrested Tenette and Gasperi, who officers say was knowingly living in a building where prostitution was taking place.

Charging documents say the informant also went to the Beijing Spa on Monday and was receiving a massage from Yu when he said she offered to have sex with him for $200.
