Gangster Ejaz Pathan, one of those convicted for the 1993 serial blasts in Mumbai, died in the city's JJ Hospital on Friday following prolonged illness.
"Ejaz Pathan is dead," Deputy Commissioner of Police Brijesh Singh told PTI without giving details.
Pathan, who provided his men to absconding main accused Tiger Memon for landing RDX on the Raigad coast ahead of the 1993 blasts, was sentenced to rigorous imprisonment for ten years by the special TADA court on June seven.
Pathan was suffering from various ailments, including blood clots in the brain, and had suffered a paralytic attack earlier.
A one-time associate of fugitive gangster Dawood Ibrahim, Pathan was present at the first meeting in Dubai of those behind the conspiracy to carry out the 1993 blasts where it was decided that the demolition of the Babri mosque in Ayodhya was to be avenged.
However, while sentencing Pathan, TADA Judge P D Kode had said there was no proof that he was involved in later stages of the conspiracy.
Pathan fled to Dubai in 1993 and was extradited in 2003. He reportedly fell out with Dawood later on.
He had many health problems, including heart disease, diabetes and a neurological problem.
The last was the result of a bullet injury Pathan sustained when Dawood's men allegedly attempted to kill him in Karachi in 1998.
