According to the "Financial Times" report, South Korean prosecutors asked Interpol to issue a red notice against Do Kwon, and said that Do Kwon refused to cooperate with the investigation of the UST and LUNA crashes. The Seoul Southern District Prosecutor's Office said it had asked the Ministry of Foreign Affairs to cancel Do Kwon's South Korean passport and had begun the process of putting him on an Interpol red notice and having his passport revoked. The red notice represents that when a country has a bilateral extradition treaty with the country concerned, the criminal suspect can be temporarily detained, which is the highest level of emergency notification. After receiving the red notice, each Interpol member country can immediately arrest the wanted person and carry out international extradition in accordance with the relevant laws of the country.
