Source text: In a span of less than 24 hours, Tokyo and Hong Kong were targeted in significant cash robberies, with ¥420 million stolen in Tokyo and ¥51 million in Hong Kong. Authorities swiftly arrested three suspects at Hong Kong International Airport as they attempted to flee. Additionally, two employees of a cryptocurrency exchange in Tsim Sha Tsui were detained for allegedly aiding in laundering the stolen funds. The arrested individuals include a 28-year-old local man and a 29-year-old from mainland China. Preliminary investigations suggest a Japanese company may have been involved in smuggling yen into Hong Kong to exploit tax differentials by purchasing tax-free goods.
