"I have no faith in the investigation by the state police. The probe should be handed over to the CBI for an impartial investigation," he said on Sunday.
The petition has been filed against several police officials, district administration and doctors treating the victim and officials of the State Forensic Science Laboratory for allegedly giving false reports on the gang rape.
The girl, a resident of Sorisapadar village, was allegedly gang raped by a group of security personnel on October 10 last year when she was returning from Kunduli market near the village in Koraput district. She committed suicide at her house on January 22.
The family members alleged that she hanged herself as she was denied justice by the state government.
Meanwhile, a team of the National Commission for Scheduled Castes (NCSC) arrived in Odisha on Sunday to probe the case and will visit the victim's village.
