Amravati police commissioner Arti Singh said the murder of chemist Umesh Kolhe, prima facie, seemed to be the fallout of the backlash against Kolhe's social media campaign in support of Nupur. She clarified that the motive could be confirmed only after interrogating the mastermind, Irfan Khan, a school dropout who runs the Amravati-based NGO Rahbariya Foundation and provides a free ambulance service to underprivileged Muslims through a helpline.
