As Alam reached the Dental College dorm at Sobhanbag as instructed by the caller, he found his son laying on the floor beside the stairs on the ground floor.
The students there claimed that Rana went there to steal a cell phone. The students then made him sign a blank paper before handing over his son to him.
Alam took him son to a local clinic and later transferred to Dhaka Medical College Hospital where doctors declared Rana dead at 11:00pm.
Rana' elder brother Rezwan Alam Ronny said the cell phone that Rana was carrying has been missing. "Some unknown people of the Dental College answered when I called that cell phone."
