The anti-terror probe agency NIA will investigate the killing of a chemist in Maharashtra's Amravati, the government said on Saturday, after it emerged it might be linked to his social media posts supporting suspended BJP leader Nupur Sharma. The chemist, Umesh Prahladrao Kolhe, was killed on June 21. A Home Ministry spokesperson tweeted that the probe of the case relating to the "barbaric killing" of Kolhe has been handed over to the National Investigation Agency (NIA).
