The four convicts sentenced to death in the Nirbhayacase will be hanged January 22 at 7 am, said a Delhi court on Tuesday, issuinga death warrant.

Akshay Thakur Singh, Mukesh, Pawan Gupta and VinaySharma were found guilty in the 2012 gang-rape, torture and killing of a youngmedical student in Delhi.

Nirbhaya's mother, who had petitioned the court fora death warrant said that she had waited seven years for justice adding that thisjudgement will reinforce people's faith in the judiciary. My daughter will getjustice.

Last month, the Supreme Court dismissed the lastreview petition in the case, filed by Akshay Singh. Nirbhaya's parents thenasked a lower court to issue a death warrant but the judge had deferred adecision until today.

Nirbhaya's mother wiping her tears said, "Ihave been running from pillar to post for one year," and wept at the timebefore the judge, who consoled her saying he was bound by the law.

Besides the four convicts, two more were accused inthe rape and murder. Ram Singh, the fifth accused, committed suicide and ajuvenile was released after three years in a reform home.

The 23-year-old paramedic student was gang-raped andtortured with an iron rod on a moving bus in south Delhi on December 16, 2012,before being dumped on a road, naked and bleeding. She died on December 29 amidstreet protests across the country.

Dismissing the review petition of the convict, theSupreme Court had said: "Review petition is not re-hearing of the appealover and over again." The three-judge bench had pointed at similararguments considered for petitions of the three other convicts.
