A day after a police officer was killed in mob frenzy over cow carcasses found near a village in Uttar Pradesh's Bulandshahr, chief minister Yogi Adityanath chaired a security review meeting late on Tuesday night, but kept the focus firmly on cow slaughter. Inspector Subodh Kumar Singh was attacked with stones and shot dead by a mob of hundreds that chased his car and surrounded it in a field. The officer and his team had gone to the area to tackle protests after cow carcasses were found scattered in a forest.
