An unconscious man in his 20s was dragged by his hair to a cycle rickshaw and held there under a policeman's boot while being taken to a hospital after he was thrashed by a mob of police and locals. He had brandished a gun at them, officials said.
The incident occurred on Tuesday in the district headquarters town of Munger, 136 km from the state capital.
The youth, identified as Mohammad Afroz, was engaged in a brawl with another youngster near Kotwali police station. He was allegedly inebriated at the time.
As a traffic constable, Mohammad Abbas, tried to break up the fight, Afroz, a resident of Ghasiyar mohalla, whipped out a 9 mm pistol and tried to fire at Abbas, reports said.
Thereafter, Afroz was overpowered by the crowd, and the pistol, along with two loaded magazines and five live cartridges, were recovered from him. The police and locals beat him up till he lost consciousness, and tied up his hand and feet. Next, he was dragged by his hair to a rickshaw by a policeman who pinned him on the floor under his foot and took him to Munger Sadar hospital.
Munger superintendent of police P Kannan said the man in uniform had been identified as constable Ambika Prasad.
"He has been placed under suspension and an investigation has been ordered," he said.
Bihar BJP chief CP Thakur described the incident as 'barbaric'. State Congress president Chaudhary Mehboob Ali Kaisar said the incident and behaviour was totally 'unacceptable'.
