The Public Security Directorate in Lebanon was established in 1945 under the leadership of Commissioner Edouard Abu Joudeh, following a period when the Lebanese Police Directorate was responsible for state and citizen security in Beirut and other cities, with a specialized judicial section handling criminal investigations. Prince Farid Chehab played a prominent role in developing and organizing public security, particularly in combating crime and espionage during the French Mandate era. The Public Security Directorate was tasked with monitoring public policy, foreigners, borders, drug and weapons control, and coordinating with the army and judicial police. Prince Farid Chehab led the directorate during a critical period, successfully uncovering complex crimes and strengthening national and political security. He also served as governor of the Bekaa region to resolve local disputes. Today, Public Security is a sophisticated national administration that respects human rights and operates transparently.
