Just a week before the presidential election date, the opposing party alleged that the public servants from National Intelligence Service (NIS) have organized to promote Park's election campaign by way of posting online articles favorable to Park and slanderous to the opposing candidates. This political behavior by public servants is strictly prohibited by Korean Constitution. To prove their allegation, the opposing Democratic Party, along with the police and Central Election Assistance Commission, swooped in the house where the alleged agent of NIS has resided. From there, the 29-year-old female agent, later known as Ha-Young Kim, who was running an illegal online election campaign operation such as spreading slanderous postings about the opposing candidate had locked herself in. The police could not force to enter the house and the standoff lasted for three days, provoking a tense political standoff. The opposition accused the intelligence service of blocking an investigation. Park and her party accused the opposition of harassing the woman. Park even said the standoff of the self-lock-in was a violation of a female right in the presidential candidate debate that took place three days before the election.
