Not to be confused with the Korean Mob from GTA IV.
The Kkangpae (Korean: 깡패) is a South Korean criminal gang based in Los Santos, appearing in Grand Theft Auto V and GTA Online. They can be found on Ginger Street in Little Seoul, usually by the apartment complex across the street from the car wash/convenience store.
The name Kkangpae literally translates into "Thug" in Korean language, and usually refers to unorganized street gangs, like the group depicted in-game.
Like most gangs, they will become hostile and shoot if the player hangs around too close.
