How do you start a gang fight on gta sa?

The gang territories do not work in GTA IV as they do in GTA San Andreas. Although you do occasionally see shootouts spontaneously going on between various factions when you walk the streets. However, you can start your own fighting melee with Niko if you go to various potentially volatile areas like Hove Beach and Alderney City "Korea town" for example. Hove Beach is full of gangster types, if Niko can harrass them enough to start a fight (by kicking a car in a traffic queue, or pushing someone around, for example), he can lead them into conflict with the police and all hell will often break loose. He only has to run towards a cop or cop car, or police station, and let one or gangsters take a swing at him, and the cops will attempt to arrest the gangsters (as long as Niko doesn't fight back), but of course often the gangsters will not go quietly. Niko can also cause trouble if he rushes into the Perestroika Club in Hove Beach and starts shooting. This usually causes uproar. In Korea Town in Alderney City, the gangsters are just as touchy. One thing you have to be careful of is the fact that many of these gangster and mafia types carry knives firstly, and guns secondly, but they usually start with the fists first.
