As night curfew makes a comeback in Kolkata, the cops have asked restaurants, bars, shops and other establishments to down the shutters by 10:30 PM. Following orders from state administration, the police has warned of a strict action against those who do not do so. With Diwali round the corner, special measures have been planned to combat the violations of night restrictions and traffic rules, especially over speeding and drink driving. The police is planning to step up checking at city’s entry points in order to ensure better implementation of night restrictions as well as keep a tab on the entry of the banned crackers in the city.
