Ramna police led by Metropolitan Magistrate Mohammad Rafiqul Islam yesterday exhumed the body from Azimpur Graveyard four days after his death on Tuesday.

Physicians of the Department of Forensic Medicine at Dhaka Medical College today perform an autopsy on the body.

Teachers of Nayatola Government Primary School on July 2 beat up their class four student Dipu, who died at Ad-Deen Hospital in Maghbazar in the capital.

Jahanara Begum, Dipu's mother, on Thursday filed a murder case against two teachers and Ramna police arrested Headmistress Shaheena Akhter and Assistant Headmaster Khorshedul Haq Khasru the same day. They were taken on a three-day remand on Friday.

The teachers claimed during interrogation they are not responsible for Dipu's death and they used to treat him like other students, said the officer-in-charge of Ramna Police Station.
