Liberty City Police Department
The Liberty City Police Department is the police department for Liberty City. In the GTA III era rendition of Liberty City there are three stations: one on Portland Island, one on Staunton Island and one on Shoreside Vale. In the GTA IV rendition of the city there are 15 stations: 1 station in Broker, 2 stations in Dukes, 2 stations in Bohan, 7 stations in Algonquin, 3 stations in Alderney
in GTA III, the LCPD had bases in Portland Island, Staunton Island and Shoreside Vale (with the Staunton Island Station serving as Official Headquarters). There are three known police officers in the LCPD: Police Chief Jim Ramirez, Leon McAffrey and Ray Machowski. keeps track on the criminal elements in Liberty City, and focus primarily on the mafia families (the Leone family, Forelli family and Sindacco family). In 1998 they are tracking Vincenzo Cilli, Toni Cipriani and Salvatore Leone. In 2001 they continue to track Toni and Salvatore, but also concentrate on Joey Leone and Luigi Goterelli, along with investigating the gang problems in the city. The LCPD appears to be under funded by Mayor Miles O'Donovan, as they only receive helicopters in April 2001. 
Leon McAffrey is a corrupt police officer, who is involved in selling stories to the Liberty Tree newspaper and in helping various gangs. The first can be seen on the Liberty City Stories website , whereas the second can be seen during Liberty City Stories (as he helps the Leone family and the Uptown Yardies). An investigation is launched into corruption within the LCPD, and McAffrey is place under arrest. He later turns evidence to the state about fellow corrupt officer Ray Machowski, which leads to his death in Plaster Blaster in Grand Theft Auto III.
Ray Machowski is another corrupt police officer, who was straight but later became a corrupt officer. He begins to work with the Yakuza, but in 2001 he has been ratted out by Leon McAffrey. He employs Claude to kill McAffrey and then assist him in his escape from the city.
The Liberty City Police Department in GTA IV is about 40,000 officers strong, in many different roles, most notably on beat patrol all throughout Liberty City. They include Highway Patrol Units (while usually freeway/bridge duties are transfered to a State Police agency)tactical response units (SWAT and NOOSE tactical units), aviation units, undercover groups (mainly anti-drug and gang groups) and marine/boating units. The aviation branch of the LCPD (formed in 2001) has a fleet of several helicopters (consisting of Maverick type copters) always on 24/7 Patrol, from more than 4 Operatoinal Air Bases positioned throughout Liberty City (They take the LAPD rational of always having helicpoters on stand-by, yet none of their helicopters are ever found parked on helipads, instead NOOSE Annihilators are positioned on helipads). The Police Mavericks can be seen often in the skies of Liberty City, most often patrolling above major bridges such as the Hickey Bridge and East Borough Bridge. The LCPD is otherwise underfunded, unable to afford specialized pursuit vehicles and as a result have to use their regular patrol cars to chase suspects. They are known for its very aggressive techniques in pursuing crime, most notibley, saturating an affected area of high crime rate with dozens of officers and patrol cars. They take the famous NYPD rational, of having visible officers around every corner and virtually in cars on every other street.
LCPD officers are sometimes seen writing tickets (as noticed around Middle Park) and in highway patrol duties on the various bridges (perched over waiting for speeders or giving tickets). Officers on foot patrol are sometimes seen chasing and apprehending criminals, which after they are caught, a radio car is contacted to take the criminal away. The LCPD is also on an active recruiting campaign, with "Join The LCPD" posters and billboards on select locations throughout the city, and adorning the front of the LCPD/NOOSE substation and LCPD Star Junction Sub-Station, (which is infront of a Liberty City Services Booth). They will also appear in the streets by dialing 911 to summon a police car with two officers inside. One officer will check around for any incidents. If a criminal attacks an officer, two officers will wield pistols and go after the criminal and catch him/her at gunpoint. If there are'nt any criminals around, he will get back inside of his cop car and drive off.
