Former Central Bureau of Investigation (CBI) Director and Nagaland Governor Ashwani Kumar was found hanging at his residence in Shimla on Wednesday evening, officials said. Kumar, a 1973-batch IPS officer, became CBI Director in 2008, succeeding Vijay Shanker, in the middle of its probe into the Aarushi Talwar murder case. He was later appointed Governor of Nagaland. He was serving as the Vice-Chancellor of a private university in Shimla. Ashiwini Kumar investigated the infamous Aarushi Talwar murder case. He also initiated a probe into the alleged Commonwealth Games scam, and it was under his tenure that a charge sheet in the alleged Sohrabuddin fake encounter case was filed against now Home Minister Amit Shah. Shah has since been discharged in the case.
