At a press conference in the city, Munkir Nayeem Sunny, a second year student of Notre Dame College, said his father Obaidur Rahman Shyamal killed their mother Sultana Yasmin Mani at their residence at Baridhara at about 3:00pm on June 18 and then hung her body from a ceiling fan with a scarf to make it look like a suicide.

He also alleged that his father had also manipulated the postmortem report, which said that Mani committed suicide, although there were injury marks in different parts of the body, including her chin.

His father's shady dealings with some unscrupulous officials has made all this possible, he added.

He also demanded that autopsy be performed on his mother's body again to find out the real cause of her death.

Nayeem said his father often tortured his mother in order to take landed property of her parents under his possession.

He also alleged that some police officials of Cantonment Police Station are not taking the case seriously as they have some understanding with his father.
