Four Nashville area massage parlors were raided Monday afternoon in connection to a prostitution case.
Officers simultaneously raided Golden Massage on Abbott Martin Road in Green Hills, Daily Massage on North Gallatin Pike in Madison, ABC Massage on Franklin Pike in Berry Hill, and Acupressure Treatment Center on 4th Ave South near downtown.
Three women face felony charges, while seven others received misdemeanors.
Detectives are investigating whether women working at the four massage parlors were being trafficked.
Police said they had been investigating the local businesses for weeks prior to Monday's raid after receiving complaints and determining sex acts were being performed for money.
Authorities said any "Johns" who visited the establishment could also face jail time.
"It sends an important message if anyone has frequented these businesses for illegitimate activities that are against the law your name may be on file inside the business," Metro police Captain Mike Alexander said.
Nashville's News 2 found ads for all four businesses on the Web site Backpage.com.
One local business owner in Berry Hill near ABC Massage told News 2 he hadn't noticed anything out of the ordinary. He said the business attracted mostly men but was "quiet."
A woman who works in the area told News 2 she received a massage at ABC Massage but never went back. She said it was very dimly lit inside, making her feel uncomfortable, but there was nothing that led her to believe there was sex trafficking going on.
Xiufang Lu, 51, Ping Wei, 48, Ying Lin, 25, are charged with felonies of promoting prostitution and trafficking for commercial sex. They are being held in lieu of $100,000 bonds.
Jing Xiau, 28, Aizhen Jiang, 50, Yuan Yv, 26, Guangyun He, 46, Shi Yajun, 51, Yuzi Cui, 51, and Yan Li, 49, are all charged with prostitution and are being held in lieu of $10,000 bonds.
The investigation is ongoing and additional arrests are expected.
