A young man reportedly assaulted three police personnel, including the officer-in-charge (OC) of Pallabi police station, in the early hours of Tuesday.
According to police, the attack occurred on the station premises, leading to the arrest of the assailant, Abdur Razzaq Fahim, along with three others.
The injured policemen are OC Nazrul Islam, Sub-Inspector Shariful Islam, and ASI Md Nasir.
According to DMP Deputy Commissioner (Mirpur Zone) Maksudur Rahman, the incident took place around 12:30am.
He said Fahim arrived at the police station and informed the duty officer that a murder had occurred in the area.
OC Nazrul clarified that no such incident had taken place, and explained that a young man had been stabbed and was receiving treatment at a hospital, while the perpetrator was already in custody.
Fahim, appearing agitated, accused the officers of concealing the truth and insisted that the duty officer was aware of a murder.
When OC Nazrul asked for his identity, Fahim hesitated to disclose it.
As the OC attempted to escort him to his office, Fahim reportedly launched a physical attack, punching and kicking the officers.
As ASI Nasir intervened, he sustained a broken finger in the scuffle.
Fahim also allegedly punched SI Shariful in the forehead before being subdued and detained.
Following his arrest, Fahim reportedly revealed that three others were travelling with him in a car from Gazipur, which had a news channel's sticker on it.
All four individuals were brought to the police station and later arrested.
A case has been filed against them, said DC Maksudur.
The injured officers were taken to Kurmitola Hospital for treatment.
