History
Much before the Independence, superior police officers belonging to the Imperial Police (IP) were appointed by the Secretary of State on the basis of competitive examination. The very first open civil service examination for the service was held in England in June, 1893 and the top ten candidates were appointed as probationers of the Indian (Imperial) Police. However, it is not possible to pinpoint a date on which it could positively be claimed that the Indian Police came into being. In around 1907, the Secretary of State’s officers were directed to wear the letters "IP" on their epaulettes to distinguish them from the other officers not recruited by the Secretary of State. In this sense, 1907 could be regarded as the starting point for the Indian Police.
