None arrested yet

Jahangir Miah, the investigation officer (IO) of this case claimed that a mobile set went missing from the dormitory half an hour before the incident.

Dormitory students might have killed Rana suspecting him to be the stealer, as stealing is a frequent incident in the dormitory, he added.

"Many of our valuables went missing from the dormitory on different occasions" claimed a dormitory student.

Besides, police suspect Rana to be a drug addict who might have come to the spot to take drugs.

Family sources, however, blame Shujon, who took him to the dormitory on that day, to be allegedly involved in the murder due to previous enmity.

"Shujon deliberately killed Rana who once had beaten Shujon following some internal feuds a year back” added the family sources.

Police informed that they are yet to arrest anyone in this connection as they are not sure whether it was a pre-planned murder or mob beating.

Saiful Alam Rana, an HSC examinee, was beaten to death by Dhaka Dental College dormitory students on August 17 allegedly for stealing a mobile phone.
