Hong Kong police have launched a "code word" arrest operation, and cyber security and technology crime investigation department personnel have assisted in the search for evidence of online and cryptocurrency transactions, and have busted a local fraud group involving cryptocurrency, arresting 27 people and totaling up to HK$360 million in fraudulent funds. Yao Wing-kan, chief inspector of the Criminal Headquarters of the Southern New Territories, said that the fraud group mainly used online romance methods to lure victims into investing in cryptocurrency. The group hired technology experts to support the fraud, including local university graduates who majored in digital media, and collaborated with overseas fraudsters to build a fake cryptocurrency platform.
