A close-circuit television (CCTV) camera footage revealed more details of the fatal shooting near the Palestinian embassy in the capital's Baridhara area which left one on-duty police constable dead.

The footage shows Constable Kawsar Ahmed and his colleague Monirul engaged in a heated altercation. At one point Monirul appears to show Kawsar a duty notebook. Almost instantly, Kawsar is seen firing a round at Monirul.

Monirul immediately fell on the road. Then, as seen in the footage, Kawsar fired a few more rounds directly at him. As Monirul's body became motionless, Kawsar calmly took his gun and moved away a few steps.

Meanwhile, police today said they needed more time to find out the motive behind the killing.

"We found no previous rift between the two constables in primary interrogation. We talked to Kawsar who was punctual in his duty as per the record of the last couple of months," said Kh Mahid Uddin, additional commissioner (crime and operations).

"We are yet to find out what sparked the altercation last night," he added.

"We believe he [Kawsar] was mentally stressed," the police officer said, adding that they would be able to know the reason for the murder by interrogating the accused after he settles down mentally in a day or two.

Asked whether the constable was stressed for overwork or not getting leave for Eid, Mahid Uddin replied in the negative.

"He was not stressed or overworked as there was no pressure in duty … besides, our force members now get adequate leaves," he said.

Constable Kawsar fired eight to nine round bullets, he said replying to another query.

Meanwhile, an officer of Gulshan Police Station said preparations are underway to file a case in connection with the murder. The victim's elder brother will file the case.

The shootout took place at 11:41pm last night near the Palestine Embassy in Dhaka.

A driver of an embassy Sajjad Hossain was also shot in the incident and is now undergoing treatment at the United Hospital.

Last night around 2:30am, the Inspector General of Police (IGP) Chowdhury Abdullah Al Mamun during a visit to the spot told reporters that police recovered 20 rounds of bullets and some bullets shells from the spot.

"We are trying to find out what caused the incident," said the police chief.

Interestingly, Kawsar did not try to flee from the scene. At first, he did not allow anyone to go near him. He was later arrested by Gulshan police from the crime scene and took him into custody. Police sources said Kawsar was given food at the police station. He then spent the night sleeping in the cell.

ADC Jahangir said, "Kawsar hasn't disclosed anything yet. He is acting like a mentally distressed person. But we are hopeful to unearth the mystery behind the shooting during further interrogation."
