Citing the document, the local daily Segye Times reported on Friday that Park's former aide Jeong Yun-hoe had met with three key presidential officials to oust Kim Ki-choon, the current chief of staff to Park, without holding any official government position.

Jeong, who was the president's chief of staff when President Park was a lawmaker, regularly met with incumbent presidential secretaries and received briefings from them, the daily said.   

Cheong Wa Dae filed a libel suit against the daily and asked the prosecution to look into whether the author of the internal report violated the law on the management of public records.

Arriving at Seoul Central District Prosecutors' Office, Park vowed to answer prosecutors' questions to the best of his knowledge,

He, however, refused to comment on the author of the document and whether he had been told by his superiors to leak it. 

He denied the allegations of passing on the document but has been tight-lipped about the author.

Prosecutors said Park would undergo questioning over whether he personally confirmed the alleged meeting between Jeong and the three presidential aides and who ordered him to draw up the document.

Park has been banned from leaving the country since prosecutors opened the investigation.

A day earlier, a team of investigators from the prosecution office raided his workplace and residence to seize documents related to the allegations of the document leak. (Yonhap)
