Macau authorities arrested 10 people allegedly involved in an illegal proxy betting ring, local media reported.

According to Macau TDM, the arrested people were nabbed in casino VIP club in Macau’s ZAPE district and a residential unit in Nape. The suspects were accused of helping gamblers in mainland China bet in Macau casinos through a mobile application.

The group, which has been operating since the end of 2016, has received at least HK$6.3 million (US$805,291) in their proxy betting business, Macau authorities was quoted by the news outlet saying.

News of the arrests came almost two months after authorities broke up a similar online proxy betting ring in the special administrative region.
