Their demands also include expulsion of the killers from BUET within 72 hours and speedy trial.
The students brought out a procession on the campus around 10:30am and gathered in front of the Central Shaheed Minar on Tuesday. A group of Dhaka University students also joined the protesters around 12 noon.
Former BUET students and members of BUET Teachers' Association expressed solidarity with the students' protests.
“It is the duty of the university authorities to ensure the safety of students and others on the entire campus. Abrar Fahad’s death has proved the authorities’ complete failure to ensure the safety of students.”
On Sunday, a resident of Sher-e-Bangla Hall, Abrar was called up from his room at 7:30pm on Sunday. Later, police found his body on the first-floor stairway of the hall at 2am.
Abrar's father Barkatullah subsequently started a case against 19 people over the macabre incident after police detained ten BCL members, including BUET Chhatra League General Secretary Mehedi Hassan Russel for interrogation.
Based on its own probe, the Bangladesh Chhatra League has permanently expelled 11 members of its BUET chapter over their alleged links to the murder of Abrar, it said.
He was laid to rest in front of his home at around 11am after another funeral prayer at Central Eidgah premises in Raidanga village.
“It’s a planned homicide. They tortured him for six hours,” said Barkatullah, Abrar’s father, a retired employee from BRAC.
