These are extremely dangerous street gangs. In order to finish with them, you have to arrest every single member. Every gang has got three members. You will get 10.000 points for the first member captured 15.000 points for the second and 20.000 points for the third. But this will not be the end of them, as at the end of the game, you will discover that they have reorganised the gang again. Your mission will be to infiltrate into the gang and drive their own vehicle to capture them. Their resistance is greater than the common criminals so it will be a strength fight between your cars until you manage to arrest them.
