Relatively minor crimes committed within sight of the police may attract one star, though certain actions (like firing shots) can get the player a star if an officer is within hearing range but cannot see the player. As in previous games, the wanted level feature in Grand Theft Auto IV is measured on a six-star scale, transitioning the non-lethal one star to the extremely aggressive six stars.
The Wanted Level feature in Grand Theft Auto IV and its expansions is a measure of how much the player is wanted by the Liberty City Police Department (LCPD) or the Alderney State Police (ASP) and the game's other law enforcement agencies (such as NOOSE and the FIB) and therefore how much force will be used in the pursuit of the player.
Upon gaining a Wanted Level, a Police Search Radius is centered on the player's position.
