According to Odaily Planet Daily, the Hong Kong police recently launched an enforcement operation code-named "Double Guns", cracking down on the Hong Kong branch of a money laundering group involved in cryptocurrency in a commercial and industrial building in Tsuen Wan and arresting three men and one woman.

The criminal group actively promoted through social platforms, text messages and mobile applications, and provided attractive offers, such as "new member registration discount" or "real money in, cryptocurrency out".

The investigation found that the group has received more than HK$600 million in funds since its operation.
