SEVIERVILLE (WATE) – Three Sevierville women were arrested Wednesday after an undercover operation at a massage parlor.

Shuyan Guan, 55, Mingmei Zhang, 56, and Aihua Li, 58, are each charged with impersonating a licensed professional. Sheriff Ron Seals says officers from the Sevier County Street Crimes Unit, Knox County Sheriff’s Office Vice Unit and U.S. Department of Homeland Security conducted the investigation and found the three women, working at Chinese Pressure Massage at 732 Parkway, were not licensed to perform massages in the state of Tennessee.

The operation is part of a larger human trafficking operation being conducted by the U.S. Department of Homeland Security. The three are being held in the Seiver County Jail awaiting a court date.
