DCW chairperson Swati Maliwal said she would appeal to the Chief Justice of India, Delhi High Court and write to the President against the release of the juvenile.
"Extremely sad dat Nirbhaya's convict will walk free on 20th. Dark day in history of the county.Will be appealing to Chief Justice of High Court n Supreme Court and President to intervene. Nirbhaya rapist should not be released," she tweeted.
Maliwal stressed that an analysis needs to be carried out to assess the mental health of the juvenile convict.
"Some kind of a analysis needs to be done as to what kind of a reformation this man has gone through. We are hounded by emails, messages and calls from women who are feeling scared with the very fact that this man will come out in open, he could be travelling in a taxi or a bus. India needs to know what reformation he has gone through," Maliwal said.
He was sentenced to three years in a reform home, a punishment which drew criticism from several quarters saying it was not adequate and disproportionate in view of the heinous crime he had committed and there were demands of he being tried in an adult court.
Following the incident, government had proposed amendments to the Juvenile Justice Act, so that teenagers involved in heinous crimes can be tried as adults.
