On Tuesday morning, Al-Mamun was brought from prison to the tribunal and escorted in at about 11:30 am. Initially seated with the accused, he was later taken to the witness stand, where he read his testimony from several pages of notes. He appeared calm, occasionally referring to his papers.

In his statement, Al-Mamun described how he learned of the order. On 18 July 2024, Home Minister Asaduzzaman Khan phoned him at police headquarters and said Sheikh Hasina had instructed the “direct use of lethal weapons” to suppress the movement.

At the time, Additional DIG Proloy Kumar Joardar was with him. Proloy later relayed the order nationwide, including to then–Dhaka Metropolitan Police (DMP) Commissioner Habibur Rahman. From that day, lethal weapons were deployed.

Al-Mamun testified that Habibur Rahman and former DMP Additional Commissioner Mohammad Harun Or Rashid were particularly eager to use deadly force. He added that Asaduzzaman Khan had ordered suppression of the movement “at any cost.”

According to Al-Mamun, Sheikh Hasina was encouraged to authorise the use of deadly weapons by Obaidul Quader, Asaduzzaman Khan, Anisul Haque, Salman F Rahman, Rashed Khan Menon, Hasanul Haque Inu, Jahangir Kabir Nanak, Mirza Azam, Fazle Noor Taposh, and Mohammad Ali Arafat.
