Students in Bangladesh staged a fourth day of protests on Thursday over the killing of an undergraduate as authorities blocked an internet page that detailed alleged torture by activists of the country's ruling party.
Hundreds of students defied a heavy monsoon storm to stage a rally on the Bangladesh University of Engineering and Technology (BUET) to demand justice for Abrar Fahad.
Fahad was beaten to death on Sunday, sparking a wave of anger in the South Asian nation's universities.
Police carried out two more arrests on Thursday, taking the total detained over the killing to 15 -- including 11 from the Bangladesh Chhatra League (BCL), the student branch of the ruling Awami League.
The 21-year-old Fahad was allegedly beaten with a cricket bat and other blunt objects for six hours after he put up a Facebook post criticising Prime Minister Sheikh Hasina.
Hasina vowed Wednesday that the killers would get the "highest punishment".
Internet providers blocked a webpage launched by a BUET .
