South Korean prosecutors on today indicted Samsung’s de facto leader Lee Jae-yong on charges alleging he manipulated stock prices and violated the country’s capital-markets laws, raising the possibility that the business tycoon could return to prison.

The 52-year-old Lee, who was named along with 10 current and former Samsung executives in the prosecution’s case, won’t be arrested as part of the indictment. But he will have to stand trial in a Seoul district court. A trial date hasn’t yet been set.
