A senior police official said Falak's sister was found in Muzaffarpur in Bihar yesterday, following searches there.

The tracing of the girl, Sanobar, came after the police questioned one Laxmi, who allegedly tricked the young mother Munni into a second marriage, along with her associate Kanta Choudhry.

Police is now looking for the elder son of the woman. Laxmi had allegedly given the three-year-old girl to one of her relatives.

Laxmi and her associates had allegedly arranged her marriage with a 25-year-old youth in Rajashtan, who could not find a bride for himself. He was made to pay Rs two lakh to the women for arranging for a bride.

"Laxmi had convinced the young woman that her three children will be taken care of if she agreed to the second marriage. After her husband abandoned her, one of Laxmi's associate approached her and promised that they could arrange a second marriage.

"The woman came to Delhi where she was told that she could marry the man without telling him about her children. She was asked to tell her second husband about it later and then if he allowed, she could get back her children," the official said.
