Between 2015 and 2016, six boys aged between 8 and 16 years old went missing in the Karpi block of Arwal district in the Indian state of Bihar. Two of them returned after managing to escape their captors. They have harrowing tales to recount about how they were employed as child slaves.
The boys aren't alone in their experiences. Each year, thousands of children in India fall into the hands of the child traffickers and many of them end up as forced child laborers.
