How to File a Case Against a Large Group of People?

Question by BusinessFreak: How to file a case against a large group of people?
I live in Bangladesh. I know a group which is quite famous for road rage, reckless driving, hooliganism, bullying, mobbing, alcohol and drug abuse, as well as street-fighting. How do I enable society to punish these wrong-doers and provide justice. Pleas note that our country has laws, but they are not well regulated, and I need to be anonymous.
