Judge of Dhaka Anti-Terrorism Tribunal Md Mujibur Rahman directed Bonya and five other witnesses to appear before the court to testify.
Earlier on March 25, a Dhaka court transferred the Bangladesh-born US citizen Avijit’s murder case to the Anti-Terrorism Tribunal for trial proceedings.
Before that on March 14, the Counter Terrorism and Transnational Crime (CTTC) unit of Dhaka Metropolitan Police (DMP) pressed charges against six people, including sacked Major Syed Mohammad Ziaul Haque, a suspected coordinator of banned militant outfit Ansar-Al-Islam in the case.
The five other accused are Mozammel Hossain alias Saimon, Abu Siddiq Sohel alias Sakib alias Sajid alias Shahab, Akram Hossain alias Abir, Md Arafat Rahman and Shafiur Rahman Farabi.
Of them, Zia and Akram have been on the run.
Avijit, son of recently deceased physicist Ajoy Roy, was hacked to death, but Banya escaped with serious injuries after unidentified assailants attacked them with meat cleavers near TSC on the Dhaka University campus on the evening of February 26, 2015, as they were returning home from the Amor Ekushey Boi Mela.
Avijit’s late father filed a murder case with Shahbagh Police Station the very next day.
