The history of Solan District Police is assumed from the day, the district was formed. Solan district came into existence on 1st September, 1972 when after the re-organisation of Mahasu district some areas of Mahasu district were merged with Shimla and others formed the new district of Solan. This district is situated in the southern part of Himachal Pradesh and shares its borders with the states of Haryana and Punjab. The district is surrounded by district Sirmour in the south, Bilaspur in the North, Shimla in the East and Kalka of Haryana in the south-west sides. The total area of the district is 1936 Sq. Kms, and it has a population of 3, 39, 319 souls according to 2011 census. This district is divided into 4 Revenue Sub-Divisions viz. Solan, Nalagarh, Kandaghat and Arki.
With the formation of the Solan District, the organisation, which took care of law & order in the jurisdiction of the district, came to be known as Solan Police, and its head office was created in the center of Solan. This newly formed Solan Police, was firstly headed and supervised by Sh. I. N. S. Sandhu, IPS who joined as the Superintendent of Police on 01/09/1972. With the passage of time, the District Solan Police witnessed tremendous changes in respect of its supervisory officers, SDPO Offices, Police Lines, Police Stations and Police Posts etc.
With the advent of industrialisation in Baddi-Nalagarh area of the district, crime and pattern of crime saw a tremendous change. Migrant labour from other states posed its own challange and traffic became an increasing concern. Thus in the year, 2009 a seprate police district of BBN (Baddi, Barotiwala & Nalagarh) was carved out of the Solan district and Solan became the first district to have two Superintendent Police Offices.
Presently, the headquarters of Solan Police is situated in the heart of Solan city and is headed by a Superintendent Police who is ably assisted by Additional Superintendent of Police. Apart from them, a Deputy Superintendent of Police is positioned in the head office and two Deputy Superintendents of Police are stationed at Parwanoo and Darlaghat respectively who supervise the work of Police Stations in their respective sub-divisions.
