Wu Shuo learned that, according to the Shanghai Procuratorate's disclosure, the People's Procuratorate of Baoshan District, Shanghai, in handling a case of official misconduct, conducted a fund penetration review to trace the flow of funds and successfully filed 24 cases involving 24 individuals for supervision. The prosecutors stated that the case involved numerous underground banking gang accounts and large transaction volumes, with money laundering amounts reaching 1.8 billion yuan. The related personnel used virtual currencies to facilitate cross-border transfer of illicit funds. Ultimately, the prosecuting authorities combated the crime through arrest and prosecution, and guided the public security authorities to penetrate the fund accounts, clarify the sources and destinations of the funds, and secure electronic data, thereby improving the effectiveness of cracking down on new types of money laundering crimes such as underground banks and virtual currencies.
