107 mostly indigenous people were being held as slaves in Mexico City in a handbag and clothespin factory that was disguised as a rehab center.
The victims were severely treated and were found suffering from malnutrition and dehydration. They were fed rotten food and were not allowed to use the bathroom. Some were raped.
Some victims were brought in by their own families while others were picked up from the streets.
"There's much more going on that we don't see," TV commentator Ana Maria Salazar said. "This gives you a sense ... of stuff going on in Mexico."
