Meanwhile, a five-member team of Nationalist Lawyer Forum headed by lawyer Nishikant Mishra visited the girl's native village in Tarito under the Kishannagar police station on Tuesday and met the family members of the victim.
The Forum demanded that the family should be paid a damage of Rs 20 lakh and government job should be given to the younger brother of the victim.
Mishra also alleged that the police was "soft-pedalling" the investigation and demanded that the case be handed over to the state crime branch police.
