“After the full investigation, we will be able to confirm whether he was beaten with the intention of murder."
Monirul said: “We will complete our investigation before the deadline fixed for us by the lower court and then, the whole truth will be unveiled."

Replying to a query about police action after Abrar murder, Monirul said: "Police need permission from the authorities to enter the Buet campus.

Abrar Fahad, of the EEE department, was beaten to death inside the university’s Sher-e-Bangla Hall in the early hours of October 7.
Several Chhatra League leaders have been accused of mercilessly torturing him for hours and beating him to death, after accusing him of being involved with Islami Chhatra Shibir, the student wing of Jamaat-e-Islami.
Later, Abrar's father Barkat Ullah filed a murder case against 19 people with Chawkbazar police station.
The incident sparked mass protests among students of Buet and other universities all across Bangladesh, leading to Buet authorities banning student politics on campus.
