Indian child slavery - in pictures

Tens of thousands of girls as young as 12 are trafficked from India’s remote north east every year. Many are the daughters of tea estate workers, whose low pay means they are unable to afford to look after their families. They end up working as servants in the Indian capital New Delhi or trafficked on to the Middle East and the UK. Many suffer physical and sexual abuse at the hands of employers who keep them locked up in their homes. Few receive the wages they were promised. The trade is driven by the low wages paid to tea plantation workers, who cannot afford to keep their daughters.
