The TBI says a joint undercover operation has resulted in four arrests in East Tennessee in connection to human trafficking.

The TBI says on Friday and Saturday, authorities placed several decoy advertisements on websites that are known to be linked to prostitution and commercial sex cases.

The TBI says the focus of the operation was to identify people who are seeking to engage in commercial sex acts with females under the age of 18, and people who are trafficking victims for commercial sex acts.

As a result of the operation, the TBI says 28-year-old Aaron D. Fomby and 38-year-old Orlando Moreno-Martinez were arrested and charged with one count each of Trafficking a Minor for a Commercial Act. Both men were booked at the Blount County Jail on a $500,000 bond.

The TBI says a third suspect, 36-year-old Upen Patel, was arrested and charged with two counts of Trafficking a Minor for a Commercial Act. Patel was booked at the Blount County Jail on a $1-million bond.

A fourth suspect, 46-year-old Donald W. Turner, was arrested and charged with Promoting Prostitution. He was also booked at the Blount County Jail on a $6,000 bond.

The operation was conducted by the Human Trafficking Unit of the Tennessee Bureau of Investigation, Alcoa Police Department, Blount County Sheriff’s Office, Maryville Police Department, and the 5th Judicial Drug Task Force.
