The Police Forces of Ross and Cromarty (Ross-shire and Cromartyshire) and Sutherland merged on 16 May 1963 to form the Ross & Sutherland Constabulary. Appointed Chief Constable of the new Force was Kenneth Ross, BL, a native of Sutherland but who had served in the Renfrew & Bute Constabulary until his appointment as Chief Constable of Sutherland in 1962.
Mr Ross remained Chief Constable of the force for its entire existence, until it merged with the other Police forces of the Scottish Highlands & islands on 16 May 1975 to form the present Northern Constabulary. On amalgamation, Mr Ross became an Assistant Chief Constable of the new Force with particular responsibility for Mountain Rescue matters.
The Force wore the Scottish Constabulary crest (Semper Vigilo) cap badge throughout its existence, and the force was identified by the chromed metal insignia R&S on rails worn on the epaulettes of Constables and Sergeants above the officer's collar number.
