Kolkata: According to police, around 20-30 locals barged into a police station in south Kolkata and ransacked it while attacking cops. At least seven police personnel were left injured in the incident that occurred on Sunday night.

A senior police officer said that residents near Menoka cinema in Southern Avenue called up the Tollygunge Police Station and complained about unknown youths drinking liquor in the open and creating disturbance in the area. Police swung into action and arrested two of the accused.

The accused’s family members, mostly women, from nearby Chetla area then ramped into the police station to free the accused, the officer said.

"Instead of dealing with the matter strictly, the officer-in-charge of the police station let the duo go and only booked them under charges of disorderly conduct," the officer said.

However, the two returned to the police station with more people and "attacked" the personnel there, the officer stated.

According to the police, the accused started pelting stones at the police station and the officer-in-charge's room was also ransacked. At least seven police personnel, including women, were injured in the attack.

After city police chief Anuj Sharma vented out his dissatisfaction about the role of the officer-in-charge, the anti-rowdy section has started a search for the culprits, officers at the Kolkata Police's headquarters in Lalbazar said.

The police have lodged a suo motu case into the matter and no one has been arrested yet, a senior officer said.

"We are checking CCTV footage and some of the miscreants have been identified as residents of Chetla," the officer stated. "They are on the run and we have launched a search for them."
