Quizzed over the recent incident of ATM robbery attempt in the heart of the State capital, State additional director general of police (law and order) Ashok Kumar said that crimes rise in the winter as the roads are deserted in the night hours. “This is why we must launch regular and intense patrolling to check crimes,” he said. “I have asked the district police officers repeatedly during review meetings to intensify patrolling when the winter sets in,” he added.
