Then, Rubel was brought to the middle of staircase between the first and second floors where Major Kamruzzaman pointed a pistol on the left side of Rubel’s head and shot him. The RAB officer also shot him in the stomach. Rubel fell on the floor bleeding from his head and abdomen, and died at the scene in few minutes.
After the alleged extrajudicial killing of Rubel the team major Kamruzzaman of the RAB-10 asked his subordinate to shoot him in his left leg, however, it did not bleed and his colleagues bandaged his leg. The members of the team allegedly shot a number of blank shots. Major Kamruzzaman gave his pistol, which was allegedly used to kill Rubel, to his colleagues and ordered it be put beside the dead body. He also asked his colleagues to scatter the used bullets around the dead body, which was later taken to the Dhaka Medical College Hospital (DMCH) morgue.
After making the arrangements, the RAB asked some local people, who gathered around the building hearing the sounds of gunshots and seeing the vehicles of the RAB, to identify the deceased person. They claimed that the deceased person died in "crossfire" during a "gun-battle" between the deceased and the RAB. Showing a bandage at the foot Major Kamruzzaman claimed in public that he and his colleague constable Abdul Quader had been injured.
Contrary to the account by the RAB, the relatives of the deceased and the local people, claiming themselves as the eyewitnesses of the incident, said that no “gun-battle” took place at the time of the incident. The eyewitnesses claimed that had there have been any “gun-battle” in broad day light in a overcrowded place like Sharulia there would have been more people killed in the same incident. Besides showing the place of death, which was inside the staircase, the relatives argued that any kind of “gun-battle” was not possible inside the house.
Rubel’s older brother claimed that a person, who is reportedly an immigrant in Japan, offered a big amount of money to Rubel a few weeks earlier to kill that person's own wife named Sultana Akther Rupa. When Rubel refused to kill any person and revealed the information to the woman trying to save her life, the husband became vindictive to Rubel. The man allegedly hired Major Kamruzzaman of the RAB-10 by paying a huge amount of money to kill Rubel, who might be a witness of any case regarding the conspiracy of killing his wife.
The members of Rubel's family allege that the police and members of other law-enforcement agencies in plain clothes cordoned their house after the dead body of Rubel was brought for burial after the post-mortem. The law-enforcing agents did not allow the relatives to see the dead body and insisted them to bury the body within an hour of the arrival of the body in the evening of 17 March. The police asked the relatives not to make any noise regarding the death of Rubel anymore.
