The court had already convicted six persons including mastermind Mustafa Dossa and extradited gangster Abu Salem in the 1993 Mumbai serial blasts case, 24 years after the attacks left 257 people dead.
The court, however, had let off one accused — Abdul Quayyum — for want of evidence.
All the seven accused were facing multiple charges which included criminal conspiracy, waging war against the Government of India and murder. In the first leg of the trial that concluded in 2007, the TADA court had convicted 100 accused in the case, while 23 people were acquitted.

The trial of the seven accused — Salem, Dossa, Karimullah Khan, Firoz Abdul Rashid Khan, Riyaz Siddiqui, Tahir Merchant and Quayyum — was separated from the main case as they were arrested at the time of conclusion of the main trial.
The dastardly attacks had also left 713 seriously injured and destroyed properties worth Rs27 crore.
