Commissioners of Police currently are mandated to retire before they reach the age of 58, but may be extended upon exceptional circumstances.[2]
Early heads were often military officers or had previous policing experience in the United Kingdom or other British colonies.[citation needed] Many joined the Force in senior command postings before their promotions. Li is the only Commissioner to rise from lower ranks (as Probationary Sub-Inspector) and Hui joined as a probationary Inspector.[citation needed]
