While talking to reporters after their two-day visit here, Deputy Inspector General (Police Headquarters) of police M Ruhul Amin also said they found the evidence of fault of former officer-in-charge of Sonagazi Model Police Station Moazzem Hossain.
He said investigation against the OC and other police officers is on and it will take some time to complete it.
Mentioning that Sirajuddoula, principal of Sonagazi Islamia Senior Fazil Madrasa, had some bad track records and the managing committee was aware of those, the probe panel chief said, “This incident (Nusrat murder) would not have happened had they taken steps earlier.”
He also said local politics is also a factor behind the incident. “Two councillors of a party formed human chains in favour and against the principal.”
The five-member probe body visited the madrasa on Wednesday and Thursday, talked to its teachers, students, employees and guardians and took their opinions. They also talked to policemen and members of Nusrat Jahan Rafi.

Senior judicial magistrate Sharaf Uddin Ahmed passed the order after inspector Shah Alam of Police Bureau of Investigation (PBI), also investigation officer of the case, produced him before the court seeking a seven-day remand.
Meanwhile, another accused Abdur Rahim Sharif on Wednesday reportedly gave confessional statement in the murder case.
The same judge recorded Sharif’s statement under section 164 from 3:30pm to 9:30pm.
