At a Cabinet meeting Tuesday, President Park expressed regret over the National Intelligence Service's lax oversight, that allowed NIS officials to use forged evidence in a recent North Korean spy scandal.
"I am sorry for causing much anxiety and worry to people for the National Intelligence Service's wrong practices and loopholes in its management system."
Calling on the spy agency to revamp itself completely, President Park then said if the NIS loses the public's trust once again, she'll make sure those responsible pay the price.
Taking responsibility for directing the forgery, one of the three vice-chiefs of the intelligence agency, Suh Cheon-ho, resigned from his post,.. and President Park accepted the resignation.
NIS chief Nam Jae-joon also apologized earlier Tuesday morning, promising all-out reforms to root out corrupt practices within the agency.
"The agency will overhaul its investigation practices, and will push ahead reforms with excruciating effort, to root out all wrong practices of the past, so that this type of incident never happens again."
The apology followed the prosecution's announcement on Monday, that two documents submitted in the recent North Korean espionage case, were fabricated by the intelligence agency.
Two additional intelligence agents were charged with forging border-crossing documents that were used against a former Seoul city employee who was accused of spying for North Korea.
The 34-year-old former city employee, defected from the North in 2004, and was charged with espionage, early last year.
He was acquitted of the spy charge against him last August, but prosecutors appealed the case.
The forged documents were submitted during the trial.
Prosecutors are demanding seven years in prison for the former city employee, however, a final verdict on the case is expected to be released by the end of next week.
