Metropolitan Police Marine Policing Unit
Initially Thames Division had no Sergeants or Station Sergeants in their ranks, but instead inherited from the old River Police the ranks of 3rd, 2nd and 1st Inspector which were unique to the Division. 3rd Inspectors were paid as sergeants and were equivalent to sergeants for the rest of the force. 2nd Inspectors were of Station Police Sergeant rank and paid as such, while a 1st Inspector ranked as substantial Inspector. However, these ranks were discontinued in 1903 and Thames Division officers were then ranked the same as the rest of the Metropolitan Police, although for many years after 1903 Thames Division officers are still ranked on their service sheets using these old Inspector ranks.
