According to the police complaint, the woman was picked up by two men from the railway station on her arrival in Muzaffarnagar from Delhi on July 8 under the pretext of giving her lift.
The men then took her to an unknown location and raped her for two days. She was later sold for Rs 10,000 to a person in Solapur village in the district.
However, the woman managed to escape from the house of her buyer on Sunday.
