Some of the girls were recruited on Facebook and Instagram.
The seven girls and women ranged in age from 16 to 36. Their pimps charged $100 for a half-hour of sex, according to federal court records.
The pimps provided condoms, lubricants, rooms and cellphones, and used threats, violence, sexual assault and intimidation to control the victims, court records state. In one incident, a pimp punched a girl and forced her to remove her clothing while threatening to shoot another girl, federal agents said.
And Room 222 at a Super 8 motel in Fort Worth was a favorite spot in what federal agents called a statewide sex-trafficking operation that included young teens.
