Yan Daba, Yan Banga and Yan Daukar Amarya - A study of criminal gangs in Northern Nigeria

From the data collected, the 'Yan Daba, 'Yan Banga and 'Yan Daukar Amarya appear to operate independendy of each other. The 'Yan Daba were originally the strong arm behind various political parties, the ban on party politics and the subsequent loss of income has led them into all types of illegal activities. The 'Yan Banga, while initially assisting law enforcement agencies in apprehending criminals, has turned into a lawless force of bandits.
The 'Yan Daukar Amarya do not appear to operate out of economic deprivation; their motivation is rape.
