According to Decrypt, Europol has joined forces with law enforcement agencies from multiple countries to dismantle an illegal "Hawala" bank network that uses cryptocurrency for money laundering, involving over $23 million. The criminal group provides cash collection, cryptocurrency exchange, and cross-border fund transfer services for illegal activities such as drug trafficking and illegal immigration. 17 suspects have been arrested in Spain, Austria, and Belgium. The seized assets include $229600 in cash, $205000 in cryptocurrency, 18 luxury cars, 10 properties ($2.8 million), cigars, luxury handbags, and more. The investigation shows that the network consists of two branches: Chinese members are responsible for cash collection within Spain, and Arab members upgrade the traditional Hawala system through cryptocurrency to complete international fund transfers.
