New Delhi: Supreme Court judge Dipak Misra, who dismissed the petition and delivered the final order on 1993 Mumbai serial blasts convict Yakub Memon's death warrant leading to his execution, has received an anonymous threat letter.
Reports say that the threat letter was received by Justice Misra's guard.
A case has been registered against unidentified persons at the Tughlaq Road Police Station.
After the SC verdict, the government had increased the security of Justices Dipak Misra, Prafulla Chandra Pant and Amitava Roy.
Justice Misra headed the three-judge bench, which had upheld the death warrant against the 1993 Mumbai blasts convict.
After the verdict, the number of police personnel at their homes had been increased besides increase in patrolling by Delhi Police around their homes' vicinity.
The unprecedented hearing held at the apex court at 3 am on July 30, in which the 1993 Mumbai blasts convict's last ditch attempt to avert his execution was rejected, was the first of its kind in the SC's history and has been generally appreciated by the legal fraternity.
The execution of Yakub, whom the Supreme Court had described as the "driving spirit" behind the 12 coordinated blasts on March 12, 1993, that left 257 dead and 713 wounded, was preceded by a vigorous last-gasp attempt by his lawyers to prevent the hanging that continued through July 29 and spilled over to the early hours of July 30.
Memon was hanged at Nagpur Central Prison on July 30 at 7 am, the hour set by the TADA court for execution of his death warrant.
