Prosecutors requested an arrest warrant on Wednesday for former National Intelligence Service Director Lee Byung-kee over allegations he oversaw the transfer of millions of dollars of the agency's budget to the presidential office during the previous Park Geun-hye administration.
Earlier this week, the Seoul Central District Prosecutors' Office also requested arrest warrants for two other former NIS chiefs during the Park administration, Nam Jae-joon and Lee Byung-ho.
They are charged with causing loss of national treasury, bribery, wrongful exercise of authority, and embezzlement of public money.
According to the prosecution, the former NIS chiefs gave some 45-thousand dollars a month to the former president out of the intelligence agency's own budget.
That amount doubled to some 90 thousand dollars a month from July 2014, when Lee Byung-kee became head of the NIS.
Lee said the amount was doubled upon a request from the presidential office.
Lee later served as former President Park's chief of staff from March 2015 to May 2016.
In total, prosecutors say the three former NIS chiefs provided the Blue House with about three.six million U.S. dollars from the agency's budget for "special activities".
The NIS is exempt from having to disclose how the budget allocated for classified special activities is used.
The prosecutors are also planning to investigate Park Geun-hye to find out why the money was demanded from the NIS and how the money was spent.
