Michael Morris was part of an international sex trafficking operation that coerced hundreds of Thai women to the United States.
The 32-year-old was arrested on his way to work Thursday.
More than a dozen police departments were involved in the operation.
He was being held at a county jail on completely separate charges.
Most of the arrests were made in the Twin Cities area.
The two men have been convicted of sex trafficking of a minor.
Police found out by investigating his jail phone calls.
The research will help the fight against human trafficking.
