Former Chattogram Superintendent of Police (SP) Babul Akter lodged a complaint before a court against six officials of Police Bureau of Investigations (PBI) for torturing and attempting to kill him in police custody.

Babul, who is now in jail in a case over the killing of her wife Mahmuda Khanam Mitu, lodged the complaint against the six PBI officers with the court of Chattogram Metropollitan Sessions Judge Jebinnessa on Thursday, said Advocate Habibur Rahman Labu, counsel of Babul.

Advocate Habibur Rahman Labu lodged the complaint against PBI chief Banaj Kumar Majumdar, Superintendent of PBI Chattogram , Nazmul Hasan, Naima Sultana, inspector (Khulshi) Santosh Kumar Chakma, inspector (DB CMP) AKM Mohiuddin Selim and Police Inspector Kazi Enayet Kabir.

According to the complaint, PBI officials physically tortured Babul while he was put on  remand and tried to kill him.

On June 5, 2016, unidentified assailants gunned down Babul's wife Mitu at the port city's GEC intersection while she was going to drop her son Mahir Akhter, 7, for a bus of Chittagong Cantonment Public School and College.

Soon after the crime, Babul filed a murder case at Panchlaish Police Station against three unidentified men.

The case was transferred to the Police Bureau Investigation (PBI) in 2019 after Mitu's father, himself a retired police officer, filed a complaint against the CMP's mishandling of the case.

On May 12, 2021, the PBI submitted its final report and arrested Babul Akter in another case filed by Mitu’s father and since then he has been in prison.

Babul Akhter also filed a ‘naraji petition’ against the PBI report on October 14, 2021.

On November 3 last year, a Chattogram Court rejected the final report of PBI in the murder case and ordered it to conduct further investigation.

PBI in an investigation found Babul’s involvement in his wife's murder.
