For those who are clueless, the CBI is the government agency in charge of dealing with high-profile cases such as investigations into corruption, violations of central laws enforced by the Indian government, multi-state organized crime, multi-agency or international cases, and so on.

It is generally invested with corruption, economic crimes, certain crimes, SUO moto crimes, and other high-profile cases by the Ministry of Personnel, Public Grievances, and Pensions.

CBI: Establishment, jurisdiction, Branches:

In 1963, a home ministry resolution renamed the agency previously a part of the special police establishment, the central bureau of investigation (CBI). Though this wing was created to investigate government corruption, it has since extended its jurisdiction to include almost all high-profile cases, including murder, kidnapping, and terrorism.

It can only take such cases on a request from the state or the federal government. However, if a high court orders it, the CBI may investigate any case without first obtaining the relevant government's permission.

The investigation's central bureau is divided into six branches, each specializing in a specific area of investigation. The Anti-Corruption Division, Special Crimes Division, Economic Offenses Division, Policy and International Police Cooperation Division, Administration Division, Directorate of Prosecution Division, and Central Forensic Science Laboratory Division are the departments involved.
