The provisional post-mortem report of Faiz Usmani, who died in a hospital on Sunday after being questioned in connection with last week's serial blasts in Mumbai, has stated that he had a heart attack and there were blood clots in his brain.
"The provisional post-mortem of Usmani suggests that 90 grams of blood clot was found in his brain. He even had a heart attack. His heart has been kept separately for further medical examination," Deputy Police Commissioner (Crime) Nisar Tamboli said.
The report also says that no injury marks were found on his body, he added.
Usmani, brother of alleged Indian Mujahideen member Afzal Usmani, who is currently lodged in jail for his role in the 2008 Gujarat blasts, was picked up for questioning on Saturday by Chembur's Crime Branch unit and was rushed to a hospital at around 5:50 PM as he was not feeling well.
He died at 1:30 am on Sunday while he was undergoing treatment for hemiparesis and hypertension in the Lokmanya Tilak Hospital, doctors said.
Usmani's family alleged that he was tortured in custody.
Maharashtra Director General of Police Ajit Parasnis had ordered a CID inquiry into his death.
Usmani's son Azeem alleged that his father was picked up for questioning and "pressurised during interrogation."
Usmani's wife Rubaida said, "When the police came to take him, they said that they will just interrogate him. He had gone alone. So we don't know what the police questioned him about. I don't know to what extent he was tortured that he got so tense. They came back in an hour saying he was unwell, he had vomited and had been admitted to the hospital."
The Mumbai police have denied these charges.
"He (Faiz Usmani) was brought in for questioning by the Chembur unit. He was suffering from hypertension and had not taken medicines for the last three-four days. He was admitted to the hospital on Saturday evening. Allegations of torture by the police are absolutely untrue," Tamboli had earlier said.
Ryan Kumar, a doctor at the hospital, said, "He (Faiz Usmani) died due to a brain haemorrhage. This condition usually occurs when a person is exposed to some kind of shock".
