Police on Monday questioned Kim Seong-hoon, former deputy chief of the Presidential Security Service, over allegations that former President Yoon Suk Yeol and his wife, Kim Keon Hee, held a drinking party on a Navy vessel during their summer vacation in 2023. Kim Seong-hoon, suspected of organizing the alleged naval ship party, appeared before a special police investigation team at 10 a.m. as an abuse of power suspect. Yoon and his wife are accused of using military assets for personal purposes by holding an onboard party at the Jinhae Naval Base in August 2023. Suspicions were also raised that karaoke equipment was installed on the naval ship and firecrackers were set off at that time. The police have taken over the case from a special counsel team. Kim Seong-hoon admitted to boarding the ship during questioning by the special counsel but claimed that there was no drinking party.
