He is likely to be be hanged in the Nagpur Central Jail, where he is currently lodged, following the rejection of his mercy plea in April this year by the president, said the official who declined to be identified.
A chartered accountant, Memon, 53, has filed his second review petition before the Supreme Court which is expected to be heard July 21, but the state government is making all preparations for the hanging with the warrant issued earlier this week.
He was awarded the death sentence by a Special TADA Court in Mumbai on July 27, 2007 for his role in the blasts, including arranging finances for carrying out the 13 serial explosions which left 257 dead and over 700 injured across the city on March 12, 1993.
Subsequently, Memon - the brother of one of the main absconding accused Ibrahim alias Tiger Memon - appealed against the sentence in the Bombay High Court, Supreme Court and later filed a mercy petition with the president, followed by a review petition, and now a second review petition which is pending.
Leading criminal lawyer and a former defence lawyer in the same case Majeed Memon questioned the need for the state government's "hurry" in the matter even before the outcome of the second review petition.
"Are they pre-empting the issue or are they already before-hand aware of the outcome of the review petition? They should have waited till the matter is finally decided," Majeed Memon, a top NCP leader and Member of Parliament said on Wednesday.
