NEW DELHI: On July 30, hours before the hanging of 1993 Mumbai blast convict Yakub Memon, his brother and one of the most ‘wanted’ terrorist Tiger Memon rang up his family and discussed about taking revenge of his brother’s death. Sources inform that Tiger Memon phoned on the landline number of the family just 90 minutes before his brother was to be hanged.
The central agencies were informed about the phone after it was intercepted by the Mumbai police. Security agencies in Mumbai and Delhi have also confirmed that Tiger called up his family. Mumbai police officials after listening to the conversation identified the voice of Tiger, sources inform. Major concerns have also been raised over the probable retaliatory terror attacks as the wanted terrorist promised to take revenge of his brother’s death.
In the mean while, Supreme Court Judge Deepak Mishra who was a part of the three-member bench that rejected the mercy plea of Yakub leading to the execution has already received a death threat.
The Delhi Police has registered a case and initiation investigation after an anonymous letter was received at the doors of Justice Mishra that threatened him and mentions of an attack on him in spite of escalated security.
Believing the investigating agencies, Tiger Memon got Yakub involved in the planning and execution of the 1993 Mumbai serial blasts that killed 257 people and left over 700 injured.
After the Supreme Court dismissed his curative petition against death sentence following an unprecedented legal proceeding which went on throughout the intervening night of July 29-30, a Charted Accountant by profession, Yakub was hanged to death. 
The apex court termed Yakub, ‘the driving spirit’ behind the atrocious attack involving 12 coordinated blasts. 
Amid heavy security, Yakub Memon’s body was buried in a graveyard in Mahim area of Mumbai on the evening of July 30 and was interred at the Bada Kabristan in Marine Lines, where his father had also been buried.
