The motive for the murder of Abrar Fahad, a second-year student of the Bangladesh University of Engineering and Technology (Buet), is still unclear, said Additional Commissioner of Dhaka Metropolitan Police Monirul Islam on Thursday.
The primary investigation has confirmed that Abrar, who was allegedly beaten to death by a group of Bangladesh Chhatra League leaders, was not killed for Chhatra Shibir affiliation only, said the commissioner, who is also the head of the Dhaka Metropolitan Police's Counter Terrorism and Transnational Crime (CTTC) unit.
"We are assuming that there were some other reasons for the murder," said Monirul Islam at a press briefing at Dhaka Metropolitan Police's media center on Thursday, to give an update on the Abrar murder case.
Fifteen people, including three who have not been mentioned in the case, have been arrested so far, added the commissioner.
The three, who were not present during the murder, were arrested on suspicion of involvement, said Monirul Islam.
The police performed their duty with hundred percent professionalism, said Monirul Islam in response to a question about the professionalism of the police in going to the hall at that time but not being aware of the murder.
Monirul Islam said a police team went to the hall on hearing that there was some trouble there, but were barred from entering the hall by some leaders of the Bangladesh Chhatra League.
Abrar, 22, a student of Buet's electrical and electronics engineering department, was beaten to death allegedly by a group of Chhatra League men in Sher-E-Bangla Hall on Monday over his alleged affiliation with Chhatra Shibir.
