The doctor, who spoke on condition of anonymity, said the autopsy was done at Dhaka Medical College and Hospital Morgue yesterday. He refused to say more on the matter.

Bilkis was found hacked to death in her room at the Gulshan residence of Akbar Hossain on Friday night.

Meanwhile, police and intelligence agencies were still trying to find out clue to what actually happened on that night. Deputy Commissioner of Dhaka Metropolitan Police (north) Golam Rasul said, "Only after receiving the post-mortem report will we be able to confirm as to whether she was murdered or she committed suicide."

Police suspect that the Bilkis' son Shaheen Hossain, who came to the minister's Gulshan residence about an hour before her mother was found dead, might have killed her.

Shaheen, arrested on Friday from the minister's house, was placed on a three-day remand yesterday when

police produced him before the Chief Metropolitan Magistrate's Court, Dhaka. Gulshan police, however, petitioned for a seven-day remand.

Kabir Hossain, an orderly at Akbar Hossain's house, filed a case with Gulshan Police Station on Friday night. But he did not name anyone in the first information report (FIR).

Bilkis' nephew Nurul Islam received her body from the DMCH yesterday afternoon. She will be buried at her village home at Motihar upazila in Rajshahi.
