# Greater Chennai Police

The Greater Chennai Police, a division of the Tamil Nadu Police, is the law enforcement agency for the city of Chennai in India and the surrounding area. The city police force is headed by a Commissioner of Police and the administrative control vests with the Tamil Nadu Home Department. There are four sub-divisions of the Greater Chennai Police, and 104 police stations. The city's traffic is managed by the Greater Chennai Traffic Police. Chennai is the first city in India to introduce e-Beat system used to measure the daily routine and performance of the police personnel.

## History

In 1659, when Chennai (then called Madras) was just a group of fishing villages, Pedda Naik formed a group of peons to guard the town. By 1780 the post of Superintendent of Police was created to manage the markets. After the Indian Rebellion of 1857, the British Raj in India formed the modern Madras Police as part of its reforms.
The Chennai City Traffic Police is a branch of the Greater Chennai Police, with the mission of regulating traffic in the city of Chennai. It was established in 1929 when the Police department was split into 3, namely, Law & Order, Crime and Traffic. As of 2011, the government merged Chennai Suburban Police with Chennai city police to form The Greater Chennai Police Commissionerate.

The patrol vehicles cover an approximate distance of 3.2 km$^2$ each day.

The Tamil Nadu Police claim that the crime rate in the Greater Chennai City has come down considerably after these initiatives.
The police force include 100 Hyundai Accent patrol cars that were donated by the Hyundai Motor Company, whose factory is located in Sriperumbudur, on the outskirts of the city. The cars are fitted with digital cameras, wireless communication devices and loudspeakers, making this the only police force in the country to use sedan patrol cars. Patrol cars have been provided to Greater Chennai Police. Hyundai donated Accent cars to Chennai Police, of which 75 were given to Law & Order, 21 to traffic department. The remaining 4 cars were incorporated into the Chief Minister's convoy.
