The Salt Lake City Police Department is divided into two bureaus, which are directed from the Office of the Chief. They are the Administrative Bureau and the Operations Bureau and each is commanded by a Deputy Chief of Police. The bureaus, in turn, are divided into eight different divisions. Four of those are geographical, where the city is split into Central Patrol, Pioneer Patrol (west) and Liberty Patrol (east), and the Salt Lake City International Airport, whose police merged with the SLCPD on December 31, 2018. Additionally, staff are also allocated to the Special Operations, Investigations, Support and Professional Standards divisions.
