New Delhi, Dec 16 (NDTV): Three years to the day a young medical student was gang-raped and tortured on a moving bus in Delhi, an incident that shook India to the core, her mother revealed her name to the world, saying: "My daughter was Jyoti Singh and I am not ashamed to name her."

At a tribute for their daughter, who died 13 days after the incident on December 16, 2012, Asha Devi and Badrinath also made a passionate appeal against the release of the youngest of the six rapists, who is about to walk out of a reform home.

"I am not ashamed of taking my daughter's name. Whoever has suffered should not hide their name. It is the offenders who should be ashamed and hide their name. I want to tell everyone that my daughter's name was Jyoti Singh. From today, everyone should know her as Jyoti Singh," Asha Devi said to big applause at a public meeting in the heart of Delhi.

Speaking on the "juvenile", who is expected to be released on December 19, she said: "On her third anniversary, the culprit is being set free. Where is the justice is in that?"

Their appeal echoed in Parliament, where actor-politician Hema Malini said the "juvenile" should be given the same punishment as the other four convicts.

"The juvenile did more harm than the others. He has a devilish mind. He will not be corrected in rehabilitation. He should be punished so that everyone fears the law of the country," Ms Malini, a BJP parliamentarian, said in the Lok Sabha.

The Centre on Monday asked the High Court to extend the observation home stay of the convict, saying it needs clarity on his rehabilitation plan.

The convict was below 18 when he and five others attacked the student and her friend. He was sentenced to three years in a reform home, a punishment seen by many as disproportionate to the enormity of the crime and spurred demands for changes in the law so teenagers involved in serious crimes can be tried as adults. Four other convicts have been sentenced to death and a fifth was found dead in prison.
