Sold by her family as a teenager, Zarin was beaten, drugged and repeatedly gang-raped — just one of many thousands of young women trafficked in India.

Her home state of West Bengal — bordering Bangladesh, Bhutan and Nepal — is a key trafficking hub where more than 50,000 girls are missing, the highest figure in India, according to the latest national crime records.

Zarin, whose name has been changed, was sold to traffickers by her family after refusing an arranged marriage at the age of 16.
