The family of the Darjeeling-based woman, who jumped out of a moving train in Bihar to escape molestation, arrived in Patna on Saturday and took her home.
The woman was able to sit up and greet people on Saturday, although she had a wound on the head. The police have recorded the statements of some witnesses.
The two accused in the case, one of them an Army jawan, have been booked for molestation and abetment of suicide and sent to judicial custody.
The woman was travelling on the Dibrugarh-Delhi Brahmaputra Mail on Thursday, when she was harassed by jawan Ramesh Kumar and his aide. Unable to bear the ordeal, she jumped out of the moving train near Ara junction in Bhojpur district.
