Explanation:

The Central Bureau of Investigation (CBI) was set up in 1963 by a resolution of the Ministry of Home Affairs.

• Now, the CBI comes under the administrative control of the Department of Personnel and Training (DoPT) of the Ministry of Personnel, Public Grievances, and Pensions.
• CBI derives power to investigate from the Delhi Special Police Establishment Act, 1946.
• The establishment of the CBI was recommended by the Santhanam Committee on Prevention of Corruption (1962–1964).
• The CBI is the main investigating agency of the Central Government.
• It also provides assistance to the Central Vigilance Commission and Lokpal.
• It is also the nodal police agency in India that coordinates investigations on behalf of Interpol Member countries.
