A soldier has emerged as a key suspect in the killing of a police inspector in mob frenzy over cow slaughter in Uttar Pradesh's Bulandshahr on Monday. Police sources say they are investigating whether Jeetu Fauji, an army jawan posted in Srinagar, could have fired the shot that killed Inspector Subodh Kumar Singh. A senior officer investigating the incident told NDTV it is too soon to say conclusively that Jeetu Fauji is the one who shot inspector Singh.
