Dinesh Nandan Sahay (2 February 1936 - 28 January 2018), also known as D.N. Sahay,[1] was a police officer turned politician who served as DGP of Bihar and later as the Governor of Tripura and the first Governor of Chhattisgarh.
He was born in Madhepura, Bihar in a middle-class Chitraguptavanshi Kayastha family to mother late Kishori Devi and father late Deva Nandan Sahay and was raised in Patna. He completed his M.A. in English literature and started his career as a lecturer in the H.D. College of Arrah before joining Indian Police Service in 1960. Thereafter, he served as the DGP of Bihar state (India).
After retirement, he joined the Samata Party.[2] He was the first governor of Chhattisgarh state from 2000 to 2003. He became Governor of Tripura in June 2003. He continued on this post till 2009. Yet traditionally governors serve for five years' tenure, Sahay served one year more than a typical governor's tenure.[3] He is the father-in-law of current DGP of Bihar, Alok Raj.[4]
