On Friday, Delhi chief minister Arvind Kejriwal took to Twitter to state that convicts in the Nirbhaya case should be hanged immediately and the law should be amended so that in the cases of rape, hanging is within 6 months.

"I am disappointed that convicts in the Nirbhaya case are using loopholes in the law to avoid getting hanged. They should be hanged immediately. We are in dire need to amend our law so that in cases of rape, the hanging is within 6 months," Kejriwal tweeted.

Meanwhile, a Delhi court on Friday stayed till further orders the execution of the four convicts in the case, which was earlier scheduled to take place on February 1.

Earlier, on Friday, Tihar jail authorities filed a status report in the matter and informed the court that convicts can be hanged separately adding that convict Mukesh Singh has exhausted all legal remedies available to him.

A 23-year-old paramedical student was gang raped and murdered in a moving bus on the night of December 16, 2012, by six people, including a juvenile in Delhi. The woman succumbed to her injuries at a Singapore hospital a few days later.

One of the five adult accused, Ram Singh, had allegedly committed suicide in Tihar Jail during the trial of the case and the juvenile was released after three years in the correction centre.

The four convicts are currently lodged in Tihar Jail and the gallows have been strengthened to ensure they are all hanged together for the heinous crime they committed on December 16, 2012.
