A 12-member team from the University Teachers' Network, a platform for private and public university teachers, went to the Detective Branch (DB) office located on Minto Road in the capital on Saturday to inquire about the three coordinators of the quota reform movement - Nahid Islam, Asif Mahmud, and Abu Baker Majumder of Dhaka University.
However, Dhaka Metropolitan Police (DMP) Additional Commissioner and Detective Branch (DB) chief Mohammad Harunor Rashid did not meet them citing busy schedule.
The teachers waited for about 20 minutes before leaving.
Gitiara Nasreen, a professor in the Department of Mass Communication and Journalism of Dhaka University, said: "We came to the DB office because we are concerned about the university teacher network. We have learned from the media that three students from our university have been brought here from the hospital for extra security. We came here to find out why they were brought here from the hospital."
She added: "When we arrived, DB chief Harun was inside and was informed of our presence. But he did not meet us."
Saimum Reza Talukder, a teacher in the law department of Brac University, questioned the need for DB custody. "The students were brought here for security, but why not return them to their families? A person's safest place is with their family. If security is necessary, it should be provided around their homes and to their families," he said.
