New Delhi: One of the four death row convicts in the Nirbhaya gang-rape case, has filed a writ petition before the Supreme Court. Convict Vinay Sharma challenged the rejection of his mercy petition by the President of India, his lawyer AP Singh said on February 11.

"Vinay Sharma has filed a writ petition before the Supreme Court challenging the mercy petition rejection by President of India," Singh said.

On February 1, President Ram Nath Kovind had rejected the mercy petition of Vinay Sharma in the case. The mercy petitions of convicts Akshay Thakur and Mukesh Singh have also been rejected.

The Delhi high court on February 5 granted a week's time to the four convicts to avail all legal remedies available to them and said that the convicts cannot be hanged separately since they were convicted for the same crime.

 Later, the execution was suspended indefinitely by a Delhi court.

 A Delhi Court had issued a death warrant against the four convicts. The execution of the four convicts - Akshay Thakur, Mukesh Singh, Pawan Gupta, and Vinay Sharma -- was earlier scheduled to take place on February 1.
