Police (CIP) is senior to inspector and junior to assistant superintendent of police. In large cities, a chief inspector is the officer in charge (OIC) of a large police station. The rank insignia for a chief inspector is three stars. United Kingdom In the British police, a chief inspector is senior to an inspector and junior to a superintendent. Today, the function of chief inspectors varies from force to force. They may assist Basic Command Unit (BCU) commanders, command smaller units, or fill various staff posts. In some forces such as Hampshire Constabulary and Sussex Police, the chief inspector is the senior officer in command of a district (usually consisting of one or more local authority areas). In this respect they have replaced superintendents as the head police officer of the larger towns. Detective chief inspector (DCI) is usually the minimum rank held by a senior investigating officer (SIO), who heads major investigations (e.g. murder), and a pool of these officers usually works out of force headquarters or major police stations. The senior Criminal Investigation Department (CID) officer in each BCU usually also holds this rank. The rank badge of a chief inspector is three Bath stars ("pips") worn on the epaulettes. This is the same badge as a captain in the British Army. Until 1953, chief inspectors in the Metropolitan Police wore a crown on their epaulettes instead. Chief inspector was one of the ranks proposed for abolition in the 1994 Sheehy Report, but in the end it was retained. A number of city and burgh police forces in Scotland used the rank of lieutenant until 1948, when it was replaced by chief inspector. Metropolitan Police The rank was introduced into the Metropolitan Police in 1868 and was first used by Adolphus Williamson, the first head of the Detective Branch (later the Criminal Investigation Department). When Williamson was promoted to superintendent shortly afterwards, three of his inspectors were promoted to chief inspector and the rank was firmly established. In 1869 it was also introduced as a uniformed rank, with the senior assistant to the divisional superintendent being given the rank. The rank subsequently spread to other police forces. From 1933, every Metropolitan Police division had two chief inspectors: chief inspector (administration) and chief inspector (crime) (the latter also being a uniformed administrative officer and not replacing the divisional detective inspector (DDI)). From 1949, sub-divisional inspectors and DDIs were regraded
