A 12-year-old girl from Bangladesh has been rescued from a prostitution ring in India after she was raped by more than 200 men in just three months.

Officers said the girl's ordeal began when she failed a school subject and feared being beaten by her parents.

She ran away with the help of a woman she knew, who smuggled her across the border and sold her into the sex trade, according to police.

Police said she was first taken to Nadiad in Gujarat, where she was repeatedly abused.

Ten people have been arrested, but campaigners say the rescue is only the start.
