Rodriguez said the investigation remains open. Federal immigration authorities assisted with the raids.

The investigation began in January after complaints about prostitution and a Crime Stoppers tip about human trafficking at the massage parlors.

City Manager Jimmy Morales revoked the business licenses for each parlor.

According to a police statement, Florida has the country’s third-highest rate of reported cases of human trafficking.
