UK fraud prosecutors, fresh from their conviction of former bank trader Tom Hayes, are planning to bring criminal charges against additional individuals in the coming months.

David Green, the director of the UK's Serious Fraud Office, said on August 4 in an interview with The Wall Street Journal that he plans in the fall to file criminal charges against other former bankers for allegedly manipulating the London interbank offered rate, or Libor. He declined to comment on their identities or seniority or the exact timing.
