Police began their investigation back in October, looking into Accupressure Massage on the 17000 block of Coastal Highway and Rainbow New Spa on the 37000 block of Rehoboth Avenue Extended.
Sources told authorities that several employees of the spas promised customers sexual favors in exchange for money.
After an in depth investigation, officers obtained search warrants for the facilities and found evidence linking three employees to prostitution.
On Friday, police arrested 54-year-old Hui Wu and 57-year-old Hsiu Jung Yu, both of Rainbow New Spa along with 52-year-old Feng Ying Liu, of Accupressure Massage.
All three women were taken into custody and face a list of charges.
