Sub-divisional inspector was a rank used in the London Metropolitan Police from the 1870s or 1880s until 1949.
As the title suggests, he or she commanded a sub-division or held an equivalent administrative position.
In 1949, the rank was absorbed into that of chief inspector, although in 1953 officers who held the position of sub-divisional commander were regraded again to superintendent grade I, and are thus equivalent to modern superintendents.
Rank was indicated by a number of diamond-shaped Bath Stars (or "pips") that were worn on either the standing collar or the epaulettes.
