Shandong police have dismantled an underground banking network utilizing cryptocurrency for money laundering, marking the first such case in Dezhou. During an investigation into a telecom fraud case, police discovered the network's use of virtual currencies to transfer funds. Detective Li Weiwei played a crucial role by tracking the flow of funds and identifying a new laundering model combining traditional underground banking with cryptocurrencies. Authorities have apprehended 12 key suspects, identified over 100 financial accounts, and six cryptocurrency wallet addresses, freezing the involved assets.
