He was escorted as far as customs but left the airport before boarding his plane, he then joined a tour of the Korean border village of Panmunjom, where he ran across the border
According to a woman in the tourist group, King, dressed in civilian clothes, crossed the border, shouting "HA-HA-HA" , before running "between two of the buildings and over to the other side."

Pyongyang, August 16 (KCNA) -- KCNA issued the following report:
In the joint security area of Panmunjom on July 18, Juche 112 (2023), there happened an incident in which Travis King, a private 2nd class of the U.S. Army in south Korea, illegally intruded into the territory of the DPRK.
At 15:30 on July 18, King, who accompanied tourists to the joint security area of Panmunjom, came to be kept under control by soldiers of the Korean People's Army on duty as he deliberately intruded into the area of the DPRK side between the room for the DPRK-U.S. military contacts and the rest room of security officers along the Military Demarcation Line.
According to an investigation by a relevant organ of the DPRK, Travis King admitted that he illegally intruded into the territory of the DPRK.
During the investigation, Travis King confessed that he had decided to come over to the DPRK as he harbored ill feeling against inhuman maltreatment and racial discrimination within the U.S. Army.
He also expressed his willingness to seek refugee in the DPRK or a third country, saying that he was disillusioned at the unequal American society.
The investigation continues. -0-
