Which organization among the following is single point of contact for liaison with the Interpol?

The CBI came into being during the World War II, when the colonial government felt the need to probe cases of corruption in the War and Supply Department. A law came in 1941. It became the DSPE Act in 1946. The Act to set up CBI was not passed by Parliament. It was created by an executive order of the government. In that sense, the CBI is not a statutory body. The CBI functions under the Ministry of Personnel, Public Grievances and Pensions of the central government. CBI is India's officially designated single point of contact for liaison with the Interpol.
