The body of Nazmul Hasan Sourav, a computer science student of Shyamoli Ideal Polytechnic Institute in the capital, was exhumed yesterday after seven days of burial at his family graveyard in Bangram village of Mahadevpur union in Shibalaya upazila under the district.

Earlier, the court asked police to exhume the body for autopsy as Sourav's father Amzad Hossain field a case, expressing suspicion that the 18-year-old boy was murdered at the hostel of the institute on May 19.  

“After digging up the body in the presence of Executive Magistrate Billal Hossain, it was sent to Manikganj Sadar Hospital morgue for autopsy. The reason of his death can be known after getting the autopsy report and investigation,” said Michael, sub-inspector of Adabar Police Station.

He is also investigation officer of the case.

Amzad mentioned in the case that his son lived in the students' hostel of Shyamoli Ideal Polytechnic Institute at Mohanpur under Adabar Police Station. On the night of May 19, hostel Supervisor Md Nayan called him and said that Sourav was electrocuted and he was under treatment at Shaheed Suhrawardy Medical College Hospital.

“When I went to the hospital on the morning of May 20, I saw Sourav's body covered with a sheet of cloth on a trolley in the morgue.

“When I came to the hostel to take the clothes of Sourav, I saw blood stain in front of his room. During the bathing for his burial, marks of torture were seen on different parts of the body. So I think the men of hostel authorities or Sourav's fellows killed him,” Sourav's father mentioned in the case.

Sourav's sister Urmi Hossain said, “My brother was very gentle. Two or three days before the incident, he took from our home Tk 10 thousand through bKash as a few people of the hostel pressurised him to give the money in the name of solving a trouble involving police.”

“There were marks of torture on his body and the stomach was swollen. It seems he was murdered. We demand immediate arrest and exemplary punishment of the culprits after fair investigation.”
