A federal grand jury has accused five Atlanta men of demanding protection money from Korean businesses in Gwinnett County.
Authorities said 39-year-old Eugene Thomas "Yoo Jin" Chung was the gang's ringleader. Chung and four other men have been charged with extortion, drug trafficking and firearm possession.
Prosecutors accuse Chung and his defendants of threatening the owner of a Korean restaurant by demanding payments of $400 to $800. Chung was accused of threatening to harm people and vandalize the restaurant if they were not paid.
Authorities said a victim arranged a meeting between gang leaders and an undercover FBI agent. Authorities said Chung told the undercover agent that he could offer gambling, extortion, debt collection and marijuana distribution.
It was unclear whether the defendants had lawyers.
