Mumbai serial blasts case convict Mustafa Dossa died due to cardiac arrest, hours after he was admitted to the JJ Hospital in Mumbai after complaining of chest pain.

Dossa complained of chest pain and had uncontrolled hypertension, diabetes and infection, Dr. Lahane told PTI earlier in the day. “Dossa was admitted to the jail ward of the hospital at 3 a.m.”

On June 27, 2017, the CBI had sought capital punishment for Dossa, arguing that his role in the blasts was “more severe” than that of hanged convict Yakub Memon.

The CBI said Dossa was one of the “brains” behind the conspiracy and that his degree of responsibility towards the commission of the crime was the highest.

The court, in the second leg of the trial in the blasts case, on June 16, 2017 convicted five accused, including Dossa and extradited gangster Abu Salem, under the charges of murder, conspiracy and sections of now repealed TADA, while the sixth accused Riyaz Siddiqui was convicted only under TADA Act.

As many as 257 people were killed in the co-ordinated blasts that ripped through the city on March 12, 1993. The court had acquitted another accused Abdul Quayyum of all charges.
