Two more policemen were arrested in the capital’s Razarbagh area on Tuesday night for illegally possessing a firearm and 1,100 bullets made by Bangladesh Ordnance Factory.
This is the second incident of policemen found within a week illegally possessing bullets made for official use, the Dhaka Metropolitan Police officials said.
At least five policemen of different ranks were arrested so far, the police and court sources said, while not a single officer who were in charge of arsenal, one of the most sensitive installations at Rajzargagh police lines, was  suspended, the officials said.
The subinspector (armed), Jakir Hossain, and the constable Abu Sayem were arrested by a team of Detective Branch led by its additional deputy commissioner (west) Mashiur Rahman at about 10pm on Tuesday along with the bullets and a foreign made revolver, the intelligence officials told New Age.
The bullets seized from the possession of the policemen were being used for training purpose of the force, the DMP officials said.
The incident, however, had triggered huge reaction in the police force.
DMP in a statement confirmed the arrest but did not mention the number of bullets that were seized.
DMP said that they were continuing the investigation into the matter.
The police sources said that the DB filed an arms case with the Paltan Police station at about 11pm on Tuesday soon after the arrest of the two policemen from Razarbagh police lines.  
Jakir and Sayem were deployed at the arsenal in Razarbagh, the police said. 
Chief metropolitan magistrate court magistrate Amit Kumar Dey allowed Jakir and Sayem to be remanded in police custody for seven days, the New Age court correspondent said.
On October 25, nayeks Prem Chakma, 37, of Mahalchhari in Khagrachari, and Jenal Chakma, 37, of Naniarchar in Rangamati, both deployed at the Public Order Management (north division) in Mirpur, were arrested at Karful for illegally possessing 500 bullets of AK-47 rifle made by the BOF.
A Dhaka Metropolitan Court remanded Jenal and Prem for six days in police custody following the arrest.
The DMP authorities had instituted a three-member committee, led by joint commissioner (Detective Branch) Sheikh Mohammad Maruf Hasan, to investigate the incident.
Following their interrogation in the joint-interrogation cell, the DB team had arrested another policeman Masud Miah in this connection.
CMM court magistrate Shahriar Mahmud Adnan on Wednesday allowed Masud to be remanded in police custody for six days in the case filed with Kafrul police. 
Masud had been deployed at Razarbagh before his current posting in Mymensingh, said the case plaintiff, Masudur Rahman, a Kafrul police sub-inspector.
The DB sources said that based on information from Prem and Jenal, the detectives found a number of policemen including Jakir and Sayem involved in illegally possessing and trading the official bullets, which, according to the law enforcers, are called regular bullets.
Magistrate Shahriar on Wednesday recorded the confessional statements of Prem and Jenal and sent them to jail.
Both Prem and Jenal were recruited as constables in 1998 after the Chittagong Hill Tracts Accord had been signed in 1997 during the tenure of the Awami League government.
Kafrul police sub-inspector Masudur Rahman arrested Prem and Jenal, both of them had earlier been members of Shanti Bahini and had joined the police surrendering their arms.
Masuder had filed an arms case with Kafrul Police station following the arrest while the DB were investigating into the case.
The officials said that such bullets were produced for armed forces, Border Guard Bangladesh and police.
