New Jersey US Attorney Paul Fishman says more than 30 members, associates and distributors of the Dirty Block Gang are under arrest.
Fishman says Dirty Block used extreme violence to keep competitors away.
"They were so effective in controlling the flow of illegal drugs in this area, that while better known street gangs like The Bloods and the Latin Kings are active throughout New Jersey and even in Atlantic City, Dirty Block is predominate criminal street gang in the area," Fishman said.
Fishman alleges the gang plotted to kill at least one rival.
He also says they used kids as street dealers and women as fronts and to launder their money.
