Chalapathi, a top leader of the CPI(Maoist) and a key figure in the 2008 Nayagarh armoury attack in Odisha, was killed in a gunfight with security forces at the Odisha-Chhattisgarh border. He was one of 14 Maoists killed in the encounter, which lasted for two days. Chalapathi, who had been a mystery to security agencies for decades, was eventually identified through a selfie with his wife, Aruna, found in an abandoned smartphone. He was considered an expert in military tactics and guerrilla warfare and had played a significant role in expanding the Maoist network in Odisha.
