The parents of 'Nirbhaya' called on Prime Minister Narendra Modi here today.
The Prime Minister condoled their loss and assured them that the Union Government would do its utmost for the safety and security of women.
The Prime Minister also appreciated the efforts of Nirbhaya's mother, who now runs the Nirbhaya Jyoti Trust for the security and welfare of women.
On December 16, 2012, a 23-year-old physiotherapy student was brutally gang-raped by six men, including a juvenile, in a moving bus. The woman later succumbed to her injuries at a Singapore hospital, where she had been airlifted for specialised treatment.
The case, which branded New Delhi as the 'rape capital' of the country, pushed authorities to enact tougher laws, including allowing for death sentences to be handed down to repeat rape offenders.
The four adults accused in the case were awarded the death penalty on September 13, 2013, with the Delhi High Court upholding the death penalty in March 2014.
The case is currently with the Supreme Court after the convicts appealed against the judgement.
