The World’s Biggest Crime Organizations: The Numbers Gang
The Numbers Gang are world-renown and one of the most fearsome prison gangs in the world. Operating from the Western Cape prison of Pollsmoor, the gang controls almost every prison in South Africa through violence and religion. The group is led by the 28s – in particular John Mongrel in Pollsmoor – and initiates subordinate members through forced sodomy and violence.
The numbers – 28s, 27s and 26s – all ascertain a level and function within the gang and the systematized organization is in place across the South African prison system. Insubordination results in death.
