British Columbia gaming regulators have deregistered a VIP host at the River Rock Casino Resort over suspected money-laundering violations.

On Thursday, Postmedia News reported that BC’s Gaming Policy and Enforcement Branch (GPEB) had revoked the registration of Lisa Gao, a River Rock employee since 2010 and who tended to the needs of VIP gamblers at the casino since 2012.

Gao’s responsibilities as River Rock’s director of VIP guest relations included “strategic directions and oversight of guest acquisition, development and retention.” Gao also oversaw “daily operations of all high-limit areas on property.”

The GPEB launched an investigation last November into whether Gao “acted in direct violation” of directives regarding “third-party cash buy-ins.” The decision to deregister is preliminary and a final review of the decision is pending.
