Kolkata is implementing an extensive security plan for New Year's Eve, deploying approximately 6,500 police personnel across the city. This increased presence, double that of Christmas, aims to manage larger expected crowds, prevent disorder, and ensure public safety, particularly in areas like Park Street and Central Kolkata. The operation will utilize drones, CCTV, watchtowers, and specialized teams, with senior officers overseeing divided zones to maintain order during year-end celebrations.
