The dead, Jhuma Akter, 13, lived at the house of Ebarat Hossain, brother of singer Momtaz Begum, MP at Joymontop village in Saingair upazila, police said.
Jhuma, who appeared at PSC examinations from Joymontop Government School this year, was the daughter of Riazul Islam, a day labourer.
Jhuma’s father got married again as her mother has been living in Dubai for the last two years.
Police recovered Jhuma’s body from Ebarat’s house on Thursday.
Ebarat, also a musician, said Singair police SI Ziauddin Ujjal, Jhuma used to work as a househelp alongside studying in the same school with Ebarat’s daughter. Ebarat’s son is a student of grade XI at Singair Degree College.
He, however, failed to cite any reason why Jhuma would kill herself.
Jhuma’s father, Riazul, could not be reached over phone despite repeated attempts.
Jhuma’s maternal uncle, Abu Sayeed, refused to talk about the matter. He just said the burial was done upon autopsy.
”The cause behind Jhuma’s death couldn’t be confirmed through the primary investigation. The next course of action will be taken once we receive the autopsy report,” said Singair police OC Khandaker Imam Hossain.
Meanwhile, he said, an unnatural death case was filed with the police station on Thursday night.
