ChainCatcher reported that according to a Hong Kong police briefing, the Hong Kong police recently launched an enforcement operation codenamed "Double Guns" and cracked down on a Hong Kong branch of a money laundering group involved in cryptocurrency in a commercial and industrial building in Tsuen Wan, arresting 3 men and 1 woman.

The criminal group actively promoted through social platforms, text messages and mobile applications, and provided attractive offers, such as "new member registration offers" or "real money in, cryptocurrency out". The investigation found that the group has collected more than HK$600 million in funds since its operation.
