When Rashida Bibi was 16, she left her native Bangladesh and came to Kolkata, India, with the promise of a job as a nanny.
It was a lie. In fact, she was a victim of sex trafficking.
"After giving me shelter for a few days, the family told me that they couldn't keep me and that I had to start working as a prostitute," Bibi says. Tears well up in her eyes when she remembers that moment.
Some 30 years later, Bibi is one of an estimated 11,000 sex workers in Sonagachi, a notorious red-light district in Kolkata.
