Dhaka Metropolitan Magistrate Morshed Al Mamun Bhuiyan took cognisance of the charges on Sunday and ordered that warrants be issued against absconding suspect Farooq Howladar.
The other charged in the case is Shah Alam aka Budda, who is currently in prison and has given a deposition under section 164.
Case investigation officer Dhaka Metropolitan Police (West) Inspector Sirajul Islam said he submitted the charge sheet against the two suspects to the court last week.
Another suspect, Kamal, has not been named in the case because police have not confirmed his full name or address.
The state will use the testimony of 21 witnesses to argue their case. The case investigation officer has submitted nine pieces of evidence to the court, including a mobile phone and car keys.
Rahman, an assistant superintendent of police, was found dead with a cloth wrapped around his throat near the Birulia Bridge in Rupnagar on the outskirts of Dhaka on Jun 21, 2017.
His younger brother Masum Talukdar started the murder case against several unnamed people with Rupnagar police that day.
According to the case dossier, Rahman had left his home in Uttara for work at 5 am after having his sehri meal. The location where his body was found was 15-20 minutes away from his home.
After Shah Alam’s arrest police stated the motive for the murder was hijacking.
In July, 2017, after Zakir and Mintu were killed in a shootout with police, Dhaka Metropolitan police Additional Commissioner Md Monirul Islam said that Shah Alam and three other hijackers had grabbed ASP Mizan in a private car. When he identified himself as a police officer, they killed him.
According to Monirul, Zakir had been driving at the time of the murder, while Shah Alam was next to the driver. ASP Mizan had seated in the back with Mintu and Kamal aka Farooq on either side.
They strangled Mizan to death with a cloth.
