Shiv Kumar Vaishnav, formerly a journalist, an accused in the 2011 murder case of Nai Duniya journalist Umesh Rajput, died, allegedly of hanging, while in CBI custody on Oct 4, 2016. Vaishnav and his son, Vikas, had been arrested on September 26, 2016 by the CBI, which is investigating the case on an order from the Chhattisgarh High Court. Rajput was shot dead in January 2011, after he published a story of a botched up eye operation that led to the death of an adivasi woman.
