The U.S. attorney's office says those now in custody include an alleged high-ranking leader of a faction of that gang.
U.S. Attorney Patrick Fitzgerald told reporters that Wednesday's arrests won't by themselves collapse the entrenched network of gangs in Chicago. But he says it's a step toward bringing down what he described as one of many separate pyramid organizations.
Officials say most of the suspects face federal cocaine and marijuana charges.
