The juvenile convict in the December 16 gangrape was on Sunday released and sent to an NGO at an undisclosed destination with police no longer guarding him, amid continued protest by the victim's parents.

The freedom for the 20 year-old convict came as parents of the gangrape victim continued their protest for the second day today along with activists protesting against his release and demanding death for him, according to PTI.

"We have left him with an NGO," police sources said.

IANS reported that the parents of the December 16, 2012 gang-rape victim were detained by police on Sunday while they were protesting against the release of the juvenile convict.

The victim's father Badrinath told IANS that they were taken into a bus at India Gate, and were possibly being taken outside Delhi.

"We were detained and taken in a bus from India Gate. There are around 30-35 people in this bus and we have already crossed Majnu Ka Tilla (in north Delhi)," Badrinath told IANS over phone. "I think they will take us out of Delhi," he added.

The Supreme Court will on Monday hear the Delhi Commission of Women's (DCW) plea challenging the release of the juvenile convicted in the gang-rape of a 23-year-old paramedical student in December 2012. It, however, refused to extend his detention in the remand home.

DCW chief Swati Maliwal filed a Special Leave Petition with the SC on Saturday night seeking urgent hearing against the juvenile's release. However, the apex court posted the hearing for Monday and also refused to grant stay on the juvenile convict's release.

The juvenile, who is now 20-year-old, was on Saturday moved out of the correctional home in North Delhi to an undisclosed location. He has been kept under observation of an NGO with protection from the Delhi Police, PTI reported.

Hearing on Monday

A bench of Justices AK Goel and UU Lalit will on Monday hear the petition in which Maliwal has pleaded against the convict's release until his mental reformation is ascertained, IANS reported.

"The government of India in its stand submitted that there is no material to establish that the mental state of the respondent has been reformed. His behaviour and attitude in the special home confirmed by government agencies is that the respondent continues to have a criminal/perverse bent of mind which poses a serious threat to women," the DCW wrote in its petition.

"Thus, releasing the said respondent without even calling for an assessment of his mental state may be extremely dangerous to the society," the petition added.

Although the Supreme Court has ruled against staying the convict's release on Sunday, Maliwal is hoping his release is postponed because the matter is sub-judice.

"Since the case has been registered, the matter is sub-judice now and hence the Nirbhaya rapist should not be released on Sunday. I hope the juvenile convict in Nirbhaya gang-rape case is kept in juvenile home until the case is heard," IANS quoted Maliwal as saying.

Singh's parents and several others had on Saturday protested against the release of the juvenile rapist, who was the "most brutal" among the six convicts.

Jyoti Singh was earlier referred to as "Nirbhaya", a name given by a newspaper. She was brutally gang-raped and assaulted with an iron rod on a private moving bus by six men, including the juvenile convict, on 16 December, 2012.

She had suffered severe injuries in her abdomen and intestines due to the brutal assault and succumbed on 29 December, 2012. During investigation, the police found that the juvenile was the most brutal of all the six assaulters.

While the juvenile convict was sent to a reform facility for three years, the other five were sentenced to death, a verdict upheld by the high court. Of the five adult convicts, one was found dead in Tihar Jail on 11 March. The police suspect it to be a suicide.
