A circular issued by the police chief of Uttar Pradesh has directed officials at the police station level to map and track crime according to dates on the Hindu calendar. Police chief Vijay Kumar, a 1988 batch IPS officer who was made officiating DGP in June this year, said a statewide assessment has pointed to a high rate of crime a week before new moon -- amavasya -- and the week after it. NDTV spoke to former UP police chief OP Singh for his views on the circular.
