MP Navneet Rana has sought action against Amravati Police Commissioner Aarti Singh over the June 21 killing of chemist Umesh Kolhe who had supported Nupur Sharma. Rana alleged that Singh tried to "suppress the case" by passing it off as a robbery. "After 12 days she's giving clarification on the incident...(An) enquiry must be done against [her]," said Rana.
