NEW DELHI: One of the four death row convicts in the Nirbhaya gang rape and murder case, Vinay Sharma, approached the Supreme Court on Tuesday challenging the rejection of his mercy petition by the President.

Sharma, through his counsel A P Singh, has also sought commutation of death sentence to life imprisonment.

President Ram Nath Kovind had on February 1 rejected the clemency plea of Vinay.

The trial court had on January 31 stayed "till further orders" execution of the four convicts in the case -- Mukesh Kumar Singh (32), Pawan Gupta (25), Vinay Kumar Sharma (26) and Akshay Kumar (31), who are lodged in Tihar Jail.

Pawan has not yet filed a curative petition -- the last and final legal remedy available to a person which is decided in-chamber. Pawan also has the option of filing a mercy plea.

The trial of the five convicts in the Nirbhaya case began in a special fast-track court in March 2013.

Ram Singh, the prime accused, allegedly committed suicide by hanging himself in Tihar jail days after the trial began.

The juvenile, who was said to be the most brutal of the attackers, was put in a correctional home for three years. The juvenile was released in 2015 and sent to an undisclosed location amid concerns over a threat to his life. He, when released, was 20 years old.

Mukesh, Vinay, Akshay and Pawan were sentenced to death in September 2013 by the trial court. (PTI)
