Victims were being transported from Waco and outside the U.S. to engage in illicit activities at various massage parlors in Fort Worth.

A joint investigation by the Fort Worth Police Department and other agencies led to the closure of a massage parlor for conducting illegal activity, according to police.

Fort Worth PD said its investigation into the spa showed evidence of "employees working without proper licensure" and "illegal services being offered to customers."

Fort Worth police shut down a massage parlor after discovering unlicensed employees and evidence of illegal services.
