The assailants who carried out the fatal attack on Mahmuda Khanam Mitu, wife of Superintendent of Police Babul Akter, were hired by an active police informant named Abu Musa, said Wasim and Anwar, two of the murderers.
The exact motive behind the gruesome murder is still unknown, police said.
Musa's name came up in the confessional statements that Wasim and Anwar gave before the court of Chittagong Metropolitan Magistrate Harun-ur-Rashid on Sunday.
In their statements, the duo said a total of seven people were directly involved in the murder, including themselves. The other five are: Musa, Nabi, Rashed, Kalu and Shahjahan.
But it was Musa, Wasim and Nabi who attacked Mitu on the morning of June 5, a court source quoted the confessing suspects.
The detainees also said two firearms were used in the attack, supplied by a man named Ehteshamul Haque Bhola.
A top official at the CMP, requesting anonymity, said Bhola is a leader of Swechchhasebak League in Chittagong, but refused to give further details for the sake of the ongoing investigation.
Earlier on Sunday, Chittagong Metropolitan Police (CMP) Commissioner Md Iqbal Bahar at a press briefing said police have identified all the killers of Mitu and had arrested two of the trio who directly took part in the murder.
He said all of the killers were professional. The arrested duo, Wasim and Anwar, were detained at Rangunia upazila in Chittagong.
CMP Additional Commissioner (Crime and Operation) Debdas Bhattacharia told the Dhaka Tribune that police have gathered all information relevant to Mitu's murder and are currently conducting a drive to arrest the rest of the killers.
Police also said they had not found any involvement of Abu Nosor Gunnu and Shah Zaman Robin – who were the first and second arrests in the case – in Mitu's murder. They are now in prison following the completion of their seven-day remand.
