The Supreme Court has denied 1993 Mumbai serial blasts convict Yakub Memon's review petition for transferring his death penalty to life time imprisonment.

Two years ago, the court had announced Yakub's death penalty after a series of trial. His mercy petition was also rejected by President Pranab Mukherjee last year.

Yakub, in his petition, mentioned that he had been in prison for more than 20 years, which is longer than a life term.

"It is not a hyperbole to state that he was one of the driving spirits behind the plan," said the SC in March 2013.

Over 250 people died and 700 were injured in Mumbai serial blasts in March 1993.

Yakub got arrested at Kathmandu Airport in 1994 after which he was sent for a trial and was found guilty, thus "warranting death penalty" by the court.

The investigation by CBI on the case says that the blasts were planned by Dawood Ibrahim, including Yakub's brother Tiger Memon, who is believed to be hiding in Pakistan.
