The suspects were identified as Farhad Hossain, Jalal Uddin Sumon, Kazi Akbar Ali, Saharul Islam, Aminul Islam and Monir.
Dhaka Metropolitan Police (DMP) Detective Branch (DB) Gulshan division arrested the suspects between August 6 and Saturday night. They also seized two jackets with Rapid Action Battalion
(RAB) logos, handcuffs, walkie-talkies, an ambulance, a pistol and bullets. RMG trader Sultan Hossain lived in a flat at Nakhalpara, Dhaka and his body was found hidden in a bush on July 16. The trader’s brother filed a case with Singair cop shoppe two days later.
Moshiur Rahman, deputy commissioner of DB Gulshan division, said the members of the gang would observe transactions at the banking area in Motijheel and target people who made large withdrawals.
They targeted Sultan in Motijheel on July 14 and followed him with a rented ambulance, as they had information that he had withdrawn a large amount in foreign currency.
The gang kidnapped Sultan from the Pallabi area of Mirpur by posing as members of RAB. They then took him into the ambulance and searched him for the foreign currency but did not find anything.
At one stage, Sultan began shouting for help and the abductors suffocated him inside the ambulance, according to the deputy commissioner.
After conducting a shadow investigation, DB arrested Farhad from Sakhipur, Shariatpur on August 6. Farhad confessed to the murder and detectives raided Dhaka Medical College Hospital and Paltan based on the information he provided, leading to the other arrests.
