The accused, who hails from Govandi, had come down to Thane to trade her 16-year-old daughter for Rs 5 lakh to fund the marriage of her sister's daughter, a release issued by Thane police said.
However, she was caught by officials of the Anti-Human Trafficking cell when she was about to strike a deal at a hotel here. According to preliminary reports, the woman allegedly runs a sex racket and has three daughters from three marriages.
