Victim’s father Barkatullah filed the case with Chawkbazar Police Station accusing a number of people, including BCL leaders and activists who have already been arrested over the murder, on Monday evening, said its officer-in-charge Sohrab Hossain.
Abrar, 21, a student Bangladesh University of Engineering and Technology (Buet), was found dead on the staircase of Sher-e-Bangla Hall of the university early Monday.
Some BCL leaders beat him at room-2011 of the dormitory on Sunday night suspecting his link to Bangladesh Islami Chhatra Shibir.
Police arrested the nine BCL leaders and activists over the killing after scrutinising the video footage.
They are Buet unit BCL general secretary Mehedi Hasan Russel, its joint secretary general Fuad, information and research secretary Anik Sarkar, sports secretary Meftahul Islam, Robin, Munna, Tanvirul Arefin, Amit Saha and Al Jami.
“After examining the footage of a close-circuit camera and the statements of witnesses, we’ve found the involvement of nine people in the murder,” Additional Commissioner Krishnapada Roy of Dhaka Metropolitan Police (DMP) said.
