One person is facing charges and two businesses are shut down as part of a Tennessee Bureau of Investigation human trafficking investigation.

TBI special agents served search warrants at four businesses in East and Middle Tennessee on Wednesday along with other law enforcement agencies.

Agents joined the Cumberland County Sheriff’s Department to search the C&K Spa, formerly known as QT Spa, at 801 Peavine Road in Crossville. Deputies arrested Huichu Sandve, 46, and charged her with prostitution. She was booked in the Cumberland County Jail on a $10,000 bond.

Investigators questioned two people about prostitution and performing massages without a license at both Interstate Spa at 108 Ole Patton Lane in Rockwood and Rainbow Spa at 295 Decatur Pike in Athens. They didn’t make any arrests, but agents shut down Rainbow Spa on an order from a judge. Charges are expected.

Agents also shut down Royal Therapy at 557 S. Lowry Street in Smyrna. Charges also are anticipated in that case.

QT Spa, Interstate Spa and Rainbow Spa also were the focus of an investigation in September 2013 that resulted in several arrests and citations and the closure of spas and massage parlors in East and Middle Tennessee.

The Smyrna Police Department, Cumberland County Sheriff’s Department, Rockwood Police Department, Roane County Sheriff’s Office, 9th Judicial Drug Task Force, Athens Police Department, McMinn County Sheriff’s Department and Immigration Customs Enforcement-Homeland Security Investigations assisted the TBI in serving the search warrants.
