"We will issue a memorandum to  the President, the Prime Minister and the Chief Justice on the same demand," said DRU president Nazrul Islam Mithu during the protest. Expressing disappointments over the change in the date of submission of probe report for 85 times in the last ten years, the journalist leaders said, "We do not have faith in the police over the investigation process." "Investigating officers are repeatedly failing to submit the probe report. That is why the intervention of the prime minister is needed." Besides, the leaders demanded immediate arrest of the killers and urged a united movement of journalists. Joint secretary general of the Bangladesh Federal Union of Journalists (BFUJ) Sheikh Mamunur Rashid, Dhaka Union of Journalists (DUJ) President Quddus Afrad, DUJ General Secretary Sajjad Alam Khan Tapu, former General Secretary of DRU Raju Ahmed, former Vice President of DRU Ajmal Haque Helal, former executive members of DRU Kudrat-e Khoda and Moinul Ahsan spoke at the protest rally among others.
