Later that night of the presidential debate, Kim Yong-pan, then the chief of Seoul Metropolitan Police Agency, publicly announced there was no evidence of illegal online postings from the collected laptop of the female agent. This announcement, which took place three days before the election, was believed to have significantly affected the outcome of the presidential election according to the opposing party. After months of probes into the alleged election meddling, the prosecution concluded in mid-June 2013 that Won Sei-hoon, then NIS chief who headed the intelligence agency for around four years under former President Lee Myung-bak, ordered agents to conduct an online smear campaign against opposition presidential candidates. The special investigation drew a conclusion that the agents systemically intervened in domestic politics by writing thousands of postings on politics in cyberspace through hundreds of different user IDs. Kim Yong-pan, then chief of the Seoul Metropolitan Police Agency (SMPA), was prosecuted without physical detention on charges of abusing his authority to hamper police investigation into the case. CCTV conversation between the computer analysts who were analyzing the laptop at police revealed that the police already knew there were illegal online postings against the opposing party's candidates, but the chief of SMPA publicly announced otherwise, an announcement that indicates intentional meddling into the presidential election.
