Trafficked from Bangladesh and sold into a brothel in Mumbai, Babli started learning Hindi last year at the shelter where she was put up after being rescued. She can now read, write and speak the language fluently, thanks to Hindi classes that help girls identify their trafficking routes and record more accurate testimony. ‘I was brought to Kolkata from Bangladesh, but I couldn't read the names of train stations that I crossed on my way to Mumbai’, Babli said. Two northern Hindi-speaking towns of Varanasi and Gorakhpur have been identified as hubs in the trafficking routes towards the major cities. Activists say that identifying routes is important - not only to step up police vigilance in these areas, but also to protect the girls who go back home after a court case and are once again exposed to trafficking risks. An inadvertent outcome of these lessons at the shelter is that some of the girls have obtained places in regular schools this year.
