The investigation focused on four Salt Lake massage parlors which were operated by the men, who are undocumented aliens.
Agents arrested Luis Daniel Arano-Hernandez, Manuel Zapata-Sanchez, and David Ramierz-Jiminez. The men were booked into the Salt Lake County jail on suspicion of exploiting prostitution, along with other felony charges.
Chief Deputy Attorney General Kirk Torgensen says the men allegedly used underage girls who were here illegally. It was the age of the girls that originally sparked the investigation. Torgensen believes many of the young women were victims of human trafficking - who were promised a good opportunity if they came into the country, and instead would up working in prostitution.
The suspects will be prosecuted here in Utah. The men who paid for sex could eventually be charged as well.
