At least 1,270 people were arrested for disorderly conduct from different parts of Kolkata during raids conducted early on Friday night, as revellers rang in the New Year, a police officer said.
Altogether 2,661 people were caught under different sections of the Motor Vehicles Act - 1,287 for not wearing helmets, 832 for passenger overload on two-wheelers and 174 for drunken driving, he said.
Seventy-seven others were issued non-bailable warrants for various offences.
Seventeen preventive arrests were made to avoid trouble during New Year celebrations.
Over 260 litres of liquor was seized during the raids, the officer added.
