Police have started interrogating the two suspects who were put on seven-day remand in connection with the gruesome murder of Mahmuda Khanam Mitu, wife of celebrated Superintendent of Police Babul Akter.
“Police started questioning the suspects – Abu Nosor Gunnu and Shah Zaman Robin – today [Monday] to glean more information from them regarding the murder,” said Additional Commissioner Debdas Bhattacharia of Chittagong Metropolitan Police (CMP).
Gunnu and Robin were both placed on remand for seven days by a Chittagong court on Sunday when the case investigation officer petitioned for 10 days of remand.
Gunnu, a former Shibir activist and caretaker of a shrine in Chittagong's Hathazari upazila, was arrested by police in Hathazari three days after Mitu was killed, while Robin was arrested in the city's Shital Jharna area five days after the murder.
Police claimed Robin was one of the three killers seen in CCTV footages collected from the area where Mitu was killed.
Sources said police have been scrutinising footages collected from CCTVs near the murder scene as well as other parts of the city to verify if Robin was the same person as as seen in the footages during the murder.
“Police are also working to find out the motive behind the killing and the mastermind behind it,” said a police official, seeking anonymity.
However, there has been no significant progress in the investigation; police are still not sure whether it was a militant attack or not, the police official said.
Driver of black microbus freed
Police have released Jane Alam, driver of the black microbus seen following the killers' motorcycle in CCTV footages, from their custody after questioning him regarding the murder.
Seeking anonymity, a top CMP official told the Dhaka Tribune that the microbus driver was let go, with the black microbus, as police could not find any link between the driver and the murder.
Police did not get any important information from Jane Alam even though he said he had witnessed the murder, the police official added.
Earlier, CMP Commissioner Md Iqbal Bahar on Saturday told journalists that the microbus usually went to the GEC Intersection area – where the murder took place – to pick up officials of Abul Khair Group of Companies every day and was waiting for the officials there on the day of the murder for the same reason.
Mitu, 32, was stabbed and shot to death by three unidentified miscreants in Chittagong's GEC Intersection area early Sunday morning.
Her husband Babul, who was recently promoted to superintendent of police, filed a murder case with Panchlaish police station against the three killers and their cohorts.
