I'd say the Cape Verdeans have their networks as well, but moreso in their diaspora communities. In Portugal they control a lot of the drug trade. In the south of Belgium, Rotterdam and Switzerland there have also been drug busts connected to figures from the Cape Verdean community. It's definitely not as widespread as the Nigerians and it's very much localized to areas with a Cape Verdean community - whereas the Nigerian criminals go literally everywhere even when there's no Nigerian community to speak of - but you can definitely detect CV networks active in the international cocaine trade.
The New England region in the United States, especially the cities of Boston and Brockton in Massachusetts and the Rhode Island state, is home to a sizeable Cape Verdean community. Several of the region's neighborhoods are home to street gangs. While larger and more structured gangs exist, a notable example is the gang named Cape Verdean Outlaws,[15] the vast majority of the Cape Verdean street gangs are based and named after their respective neighborhoods such as the Hendry Street Gang and the Woodward Avenue Gang.[16] These gangs sometimes cooperate, but also often rival with each other leading to murder and violent clashes over turf.[17][18][19]
The level of organization and sophistication is varying, with several gangs seldom extending beyond local crimes and drug dealing, while some others are involved in large-scale drug trafficking enterprises,[20] as well as extortion, money laundering and strong-arm jobs for locally active American Mafia crews.[21]
