Article: South Korea: The event was held in Seoul, which hosted the 1988 Summer Olympics, on April 27. Intended torchbearers Choi Seung-kook and Park Won-sun boycotted the event to protest against the Chinese government's crackdown in Tibet. More than 8,000 riot police were deployed to guard the 24-kilometre route, which began at Olympic Park, which was built when Seoul hosted the 1988 Summer Games. On the day of the torch relay in Seoul, Chinese students clashed with protesters, throwing rocks, bottles, and punches. A North Korean defector whose brother defected to China but was captured and executed by the DPRK, attempted to set himself on fire in protest of China's treatment of North Korean refugees. He poured gasoline on himself but police quickly surrounded him and carried him away. Two other demonstrators tried to storm the torch but failed. Fighting broke out near the beginning of the relay between a group of 500 Chinese supporters and approximately 50 protesters who carried a banner that read: "Free North Korean refugees in China." The students threw stones and water bottles as approximately 2,500 police tried to keep the groups separated. Police said they arrested five people, including a Chinese student who was arrested for allegedly throwing rocks. Thousands of Chinese followed the torch on its 4.5 hour journey, some chanting, "Go China, go Olympics!" By the end of the relay, Chinese students became violent, and it was reported in Korean media that they were "lynching" everyone who was disagreeing with them. One police man was also rushed to hospital after being attacked by Chinese students. On Apr 29, the Secretary of Justice, Kim Kyung Han, told the prime minister that he will find "every single Chinese who was involved and bring them to justice." Later in the day, South Korea's Prosecutor's Office, National Police Agency, Ministry of Foreign Affairs and National Intelligence Service made a joint statement saying that they will be deporting every Chinese student that was involved in the incident. China defended the conduct of the students.
