, although they could not try criminal cases. This continued until 1973. Like the Commissioner, the Assistant Commissioners were mainly appointed from outside the police until well into the 20th century, although career police officers could and sometimes did rise to the rank.

In 1878, Howard Vincent was appointed Director of Criminal Intelligence, a post that had equal rank to the Assistant Commissioners, but not the title. On his resignation in 1884, his post was replaced by a third Assistant Commissioner, the Assistant Commissioner (Crime).

, realising that the Assistant Commissioners' workload was becoming too great, appointed a fourth Assistant Commissioner, who took over some of the duties of the Assistant Commissioner (Executive). The four became known as Assistant Commissioners "A", "B", "C" and "L", heading departments with the same letter designations. Assistant Commissioner "A" effectively acted as Deputy Commissioner until 1931, when a separate Deputy Commissioner was appointed. From 1922 until 1931, Assistant Commissioner "A" was generally known as the Deputy Commissioner.

After World War I

World War I

World War I , which was predominantly called the World War or the Great War from its occurrence until 1939, and the First World War or World War I thereafter, was a major war centred in Europe that began on 28 July 1914 and lasted until 11 November 1918...

, Assistant Commissioner "B" became responsible solely for traffic and lost property, with his other former duties divided between Assistant Commissioners "A" and "L". Assistant Commissioner "L" was responsible for "L" (Legal) Department until its reorganisation in 1931. After 1931, he was renamed Assistant Commissioner "D" and became responsible for policy and planning.

By the end of World War II
