Some local Detroit gangs include the Errol Flynns, the Dexter Boys and the 7-Mile Boys, as of 2015. One of the most organized gangs to come out of Detroit was the Young Boys Inc.
The Young Boys Inc. was established in the 1970s and quickly gained control of more than 80 percent of the Detroit heroin market. At one point, the gang was grossing over $250,000 in sales of narcotics.
However, the most notorious gang to come out of Detroit is the Black Mafia Family. This gang has spread all over the United States and the correctional system, controlling much of the drug trade within.
