You would be into a pretty big trouble if you ever end up in a South African prison and you have to deal with the Numbers Gang. They are controlling most of the prisons in the country and are by far the scariest and most dangerous prison gang there is. The gang was established in 1911 and is divided into three groups - the 26s, the 27s and the 28s, each having a different role within the organisation. The 26s provides the cash, the 27s are the law-keepers and the 28s are the soldiers. What makes the Number Gang so dangerous is their affinity to violence. They are not only responsible for high number of murders of other inmates, but their members often attack the wardens and the prison guards too. This is usually left to the newest members of the gang as a mean to prove their loyalty.

Another fact that would scare many people is their extreme organisation and chain of command. If a member breaches the gang's rules he is "trialled". If he has done something serious the verdict is death by suffocation or another gang member slits his throat. For less serious violations the member will have his butthole cut, so he can start bleeding and then another member who is HIV positive will have sex with him. Honestly, I am not really sure what's worse - this or death.
