Former ministers Rashed Khan Menon, Hasanul Haque Inu, and Junaid Ahmed Palak have been sent to jail after completion of remand in connection with the murder of one Imon Hossain Gazi.
Metropolitan Magistrate Awlad Hossain Muhammad Jonayed sent them to jail on Saturday.
The court ordered their imprisonment following the submission of an application by the investigation officer, Sub-Inspector Mohammad Mahabul Islam of Jatrabari Police Station.
The trio had been in remand since November 2, with the court granting a seven-day period for further questioning.
Rashed Khan Menon was arrested on August 22 from the Gulshan area, while Inu was apprehended on August 26 from a residence in Uttara by a Detective Branch (DB) team. Palak was arrested earlier, on August 14, from the Nikunja residential area in Khilkhet after being on the run.
The murder case stems from the death of Imon Hossain Gazi, who was shot during an anti-discrimination protest on Chittagong Road in the Jatrabari area on August 5. His brother, Anwar Hossain, filed the case on August 28, naming 85 individuals, and implicating the accused in connection with the fatal shooting.
