The Sillitoe Tartan is the name given to the distinctive black and white chequered pattern which was originally associated with the police in Scotland, but which later spread to Australia, New Zealand, and the rest of the United Kingdom, as well as to some other places such as Chicago. Based on the diced bands seen on the Glengarries that are worn by several Scottish regiments, the pattern was first adopted for police use in 1932 by Sir Percy Sillitoe, Chief Constable of the City of Glasgow Police.
