The officer in charge of Tollygunge police station was removed from his chair and shifted to detective department at Lalbazar two days after mob from Chetla had attacked the police station and beaten up a constable in full public view.

The mob had unleashed violence on the police station to protest the arrest of a Chetla youth arrested for creating public nuisance.

Inspector Anup Ghosh, who was OC Tollygunge, has been posted in the detective department following a government order issued on Wednesday.

Inspector Saroj Praharaj, who was officer-in-charge of South Port police station, has replaced Ghosh.

Allegations had surfaced against Ghosh that he had deviated from the standard operating procedures he was expected to follow when the police station was under attack.

“The basic thumb rule is to alert the control room so that Lalbazar can send reinforcement from the adjoining police stations and the police headquarters. However, on the contrary, senior officers in Lalbazar had come to know of the incident through television news the next morning,” said an officer.

A day after the incident, the police station, which is located on a prominent place like SP Mukherjee Road, Calcutta police had swung into action and arrested seven persons, including two homemakers, in connection with the attack.

On Tuesday night, police conducted a special raid in pockets of south Calcutta, including near Menoka cinema, from where 15 people were arrested for disorderly conduct.

However, there were allegations that despite the spree of arrests, several youths who were seen in the footage beating and assaulting the constable, were yet to be arrested and seen moving around freely in the neighbourhood.

“We are conducting multiple raids to pick up the accused persons. There are others who are still outside,” said an officer in Lalbazar.

A prayer submitted by Calcutta police to amend the charge to a stricter section was accepted by the court on Wednesday.

Instead of Section 353 of the Indian Penal Code (IPC) that deals with deterring public servant from performing duty, Section 332 of the IPC has been added for voluntarily causing hurt to deter a public servant from performing duty.

The earlier section had a maximum punishment of two years, while the new section, if proved, could lead to a maximum punishment of three years of imprisonment.

Five people, who were arrested on Tuesday, were produced before the court on Wednesday and remanded in police custody till August 17.
