D.P. Kohli is the first CBI director who held office from 1st April 1963 to 31st May 1968. Shri Kohli was a visionary who saw in the Special Police Establishment the potential of growing into the national investigative agency.
The CBI was established as the Special Police Establishment in 1941, to investigate cases of corruption in procurement during the Second World War. Later, the Santhanam Committee on Prevention of Corruption recommended the establishment of the CBI. The CBI is the main investigating agency of the GOI. It is not a statutory body; it derives its powers from the Delhi Special Police Establishment Act, 1946.
