CBI, or Central Bureau of Investigation, is a premier government agency in India that serves as the country's main investigative body. It is often synonymous with integrity, impartiality, and efficiency. However, there are many different synonyms for CBI that can be used to describe the nature of the organization. These include Central Investigation Agency, Central Crime Investigation Department, National Investigation Agency, Directorate of Enforcement, and Serious Fraud Investigation Office. Each of these terms describes a different aspect of the organization's work, ranging from its role in investigating major crimes to its efforts to combat financial fraud and cybercrime. Regardless of the term used, CBI remains an essential institution in India's justice system.
