SEOUL, South Korea — A special prosecutor in South Korea asked state prosecutors on Monday to indict President Park Geun-hye on bribery charges, saying that Ms. Park and her secretive confidante conspired to take $38 million in bribes from Samsung, one of the world’s largest technology companies.

The special prosecutor, Park Young-soo, recommended the indictment as he announced the results of his team’s 90-day investigation into a corruption scandal surrounding Ms. Park, who was impeached by a parliamentary vote in December.

The inquiry resulted in the indictments of 30 people, including several former aides to Ms. Park, on criminal charges, including the abuse of official power. But the prosecutor could not bring any charge against Ms. Park because she is protected from indictment while in office.

His mandate now over, Mr. Park said he was leaving the task of indicting Ms. Park once she is out of office to state prosecutors.
