Three days after an Uttar Pradesh inspector was murdered in mob frenzy over cow slaughter allegations, the main accused, Yogesh Raj, remains missing. Three have been arrested. Four others arrested since the Monday incident are accused in a separate case of cow slaughter, which was filed by Yogesh Raj. Yogesh Raj, a Bajrang Dal activist, has sent out a WhatsApp video proclaiming his innocence. Inspector General Ram Kumar said evidence was required for the police to act. "We can only act on evidence. We need to forensically tests. It is not clear who shot the police officer, who shot Sumit (the second man killed in mob violence)," the police officer told NDTV.
