Rescued from forced employment, 13-year-old Lakshmi is frail and frightened.
Two child protection officers hold her on either side as she walks into the police station.
She was abducted four years ago from her village in north-east India.
Until her rescue, she had been working in people’s homes across West Delhi — cooking, cleaning and taking care of children.
“I was not allowed to rest,” she says. “If I did something wrong or it was not what they wanted, they hit me.
“If I wanted to sit down for a bit because I was so tired, they would scream at me.
“I was never allowed to leave the house, so I didn’t realise that I’m in Delhi. My employers told me that we are in Madras in South India.”
As the police and counsellors question her, Lakshmi breaks down. She tells the police that she was sexually assaulted by the men who kidnapped her.
She was threatened that if she told anyone about it, they would tell everyone back home in her village and her honour would be destroyed.
And then, when she started working the agent who arranged her work withheld all her wages leaving her with nothing.
Her uncle is just relieved to have found her. A tea garden worker from Assam, he says her parents died when she was young and her grandmother is worried sick about the young girl. He is also angry about the abduction.
“What can we really do? We are poor people — I didn’t have enough money to come to Delhi to look for my missing niece.
“Unscrupulous agents and middlemen just come into our homes when parents are away working at the tea gardens and lure young girls with new clothes and sweets. Before they know it, they are on a train to a big city at the mercy of these greedy men.”
He is not alone. One child goes missing every eight minutes in India and nearly half of them are never found. Kidnapped children are often forced into the sex trade. But many here feel that children are increasingly pushed into domestic labour – hidden from public view within the four walls of a home.
The government estimates half a million children are in this position.
At a rehabilitation home in northern Delhi run by a charity for children, Bachpan Bachao Andolan, many families have gathered.
They are all tea workers from the north-east state of Assam and have come here searching for their missing daughters.
They estimate that just from one particular area — Rangpura in Assam — 16 girls have been lost in the last three to four years.
Helping these families find their daughters is Kailash Satyarti, the head of Bachpan Bacchao Andolan.
“This is the most ironical part of India’s growth. The middle classes are demanding cheap, docile labour,” he says.
“The cheapest and most vulnerable workforce is children — girls in particular. So the demand for cheap labour is contributing to trafficking of children from remote parts of India to big cities.”
Offering them a ray of hope is the case of 18-year-old Sumila Munda, who was rescued earlier this month. The information she provided led to police arresting a couple of alleged traffickers.
