The girl, Preeti Chaudhary, while recording her statement before Chief Judicial Magistrate Ashok Kumar Gupta yesterday, had said she wanted to stay with her grandmother.
Since the grandmother, Manjula Devi, was not available in court yesterday, the girl was sent to her parents home at Madhubani.
She was escorted by the police to her grandmother's home in Karharwa village in Saharsa district by the police and her father and mother, the girl's advocate Sanjay Kumar said.
She was medically examined yesterday and found to be a minor.
Her boyfriend, 17-year-old Prashant Kumar Jha, with whom she eloped was yesterday sent to a remand home at Darbhanga.
The boy who was assumed dead had triggered violence in the district last week.
