Interpol has issued a red notice for Wong Ching-kit, also known as "Coin Young Master," a Hong Kong cryptocurrency promoter, in connection with a HK$3 million deception case. Wong, wanted for fraud and theft, became notorious in 2018 for throwing cash from a rooftop. The notice also seeks Mok Tsun-ting, an associate of Wong, for money laundering. Hong Kong police are collaborating with Interpol to locate and arrest both individuals.
