The Supreme Court on Tuesday rejected the mercy plea of 1993 Mumbai serial blasts convict Yakub Memon.

The SC bench, comprising Chief Justice HL Dattu, second senior most judge TS Thakur and Justice Anil R Dave, pronounced its verdict on Memon's curative petition on 21 July.

Memon, 53, will be hanged at 7 am on 30 July 2015 at Nagpur Central Jail, where he is currently lodged.

A special TADA court of Mumbai had in 2007 awarded death sentence to Memon on charge of criminal conspiracy under Section 120-B of the Indian Penal Code. He was found guilty of arranging finances for carrying out the 13 serial explosions across the city on 12 March 1993, in which 257 were killed and over 700 others injured.

Memon had challenged the sentencing in the Bombay High Court and later in the Supreme Court but his petitions were rejected both the times. He later filed a mercy petition to President Pranab Mukherjee, who too rejected the plea in April this year. Thereafter, Memon filed a curative petition seeking commutation of his death sentence.

Memon will be the first convict to be hanged in the 1993 Mumbai serial blasts case.
