Greensburg and State Police raided four massage parlors on Thursday and arrested two women on prostitution charges.
The parlors targeted were Mu's Asian Massage in Hempfield and Unity and Ruiquan Foot Spa and Li's Massage in Greensburg.
Trooper Steve Limani said there has been an ongoing investigation for the past month.
Patrons were allegedly offered a service that was sexual in nature.
Both agencies used undercover officers.
As a result, Greensburg police arrested 39 year old Hailan Zhou and state police arrested 60 year old Zhang Peiyun of New York.
Both women are accused of offering sexual favors for cash and were denied bail.
Police also seized cash, records and banking information.
Several other women were taken into custody by US Immigration officers because of deportation orders.
