Arrests made 200 miles away from Houston have a direct connection to the Bayou City.
Investigators say they found two men and one woman at a Portland hotel with at least three juvenile girls. They were charged with aggravated promotion of prostitution, a first-degree felony.
Authorities say they received a tip Saturday from one of the juvenile's relatives that the girls were being held against their will.
Detectives are still sorting through all the details, but they believe the group traveled there this week and posted a promotion on a website that promoted sexually-related services.
Police in Portland, near Corpus Christi, said all the victims are from Houston.
KPRC Local 2 is told that arrangements are being made now to return the juveniles to their families in Houston.
