A team of the Criminal Investigation Department is also investigating the matter
The Police Bureau of Investigation (PBI) has conducted a drive—at branches of different banks in Feni's Sonagazi upazila—to identify the source of illegal money transactions in the murder of madrasa student Nusrat Jahan Rafi.
A four-member team of PBI, headed by Chittagong Divisional Special Superintendent of Police Md Iqbal, carried out the day-long drive, on Sunday, examining the bank accounts of the accused persons in the case.
Chittagong PBI's Additional Superintendent of Police (ASP) Md Moinuddin, Noakhali PBI's ASP Basu Dutta, PBI Inspector Md Zahidur Rahman, and other administrative officials were also present during the drive.
Chittagong Divisional Special Superintendent of Police Md Iqbal said: "We are investigating whether any illegal money transactions took place in Nusrat's murder. We have inspected several banks in Sonagazi upazila including branches of Janata and Islami banks. A couple more banks in the district town will also be inspected to identify the source of the transactions."
When asked whether the team had found anything so far, he refused to comment as it is an ongoing investigation.
Meanwhile, the organized crime unit of the Criminal Investigation Department (CID) also launched a separate investigation into allegations of illegal money transactions in the murder case on April 19.
The CID team in Feni is also expected to investigate the matter.
On April 6, madrasa student and Alim examinee Nusrat Jahan Rafi was set ablaze on the roof of the madrasa by alleged supporters of the madrasa's Principal Sirajuddaula after she refused to withdraw a case she had filed against him on March 27 for sexual harassment.
The 18-year-old, with 80% burns on her body, died at Dhaka Medical College Hospital on April 10 after five days in hospital.
Following her death, 18 people were arrested, including local ruling party leaders. Seven of the arrestees have given confessional statements before the court so far.
