Nope. The closest thing is PAGAD (People Against Gangsterism And Drugs) which was a vigilante organization of mostly Muslims on the Cape Flats that arose in the mid-90s. Their "highest" point was when they murdered a gang leader, Rashaad Staggie, on live TV news. PAGAD would probably have been crushed by the police state under apartheid, but it was eventually stopped, or at least reined in, by the police.
