Meanwhile, Dhaka University (DU) teachers today underscored the need to form a speedy trial tribunal to ensure the trial of RU teacher Siddique killing case.

"It is not a matter whether Siddique was an atheist or non-atheist. A speedy trial tribunal will have to be formed to book the killers for trial," Farid Uddin Ahmed, president of DU Teachers Association (DUTA), told a human chain on the university campus this noon.

Condemning the killing, he said it is the government's responsibility to ensure people's overall security.

Maksud Kamal, general secretary of DUTA, said the RU teacher has been killed due to the failure of law enforcers. "A group of vested quarter has entered the police department," he said.

Protesting the killing, around a hundred of teachers formed the human chain in front of the Aparajeyo Bangla on the DU campus.
