A tribunal in Dhaka yesterday sentenced two people to death and four others to life imprisonment for killing Khalilur Rahman, secretary of Bangladesh National Blind Welfare Association, in 2011.
Khalilur was shot dead at Janata Housing in the capital's Shah Ali Bagh on January 1 in 2011 over the association's funds dispute.
Meanwhile, the tribunal directed the inspector general of police (IGP) to take legal action against Nibaron Chandra Barman, inspector of the Detective Branch of police and also the investigation officer (IO) of the case, for submitting a flawed charge sheet.
The death convicts are Mohammad Ramzan Ali alias Ramzan and Tipu alias Hira -- both members of the association.
The other four are Mohammad Minhaz, Hasanur Rahman Rubel, Mohammad Shahid Mostafa and Zahidul Islam alias Zahid -- all members of the same association.
Of them, Ramzan and Rubel are absconding while the others were present at the court yesterday.
The Speedy Trial Tribunal-4 also acquitted Ayub Ali, Nurul Alam Siddique, Mohammad Sohag Hossain Howlader and Yakub Ali.
Punishment of the fugitives will be effective from the day of their arrest or surrender. The convicts can file their appeals with the High Court within 30 days, Judge Abdur Rahman Sarder said.
Khalilur's wife Hasina Parvin filed the murder case against 10 people with Mirpur Model Police Station on January 2, 2011.
The tribunal directed IGP to take legal action against the IO for his negligence in investigation as he did not include Mohammad Sagor, another member of the association, in the charge sheet even though his involvement in the killing was found.
It also directed the IGP for taking necessary steps to carry out re-investigation against Sagor as early as possible.
