An "unauthorized person," Buttler writes, was able to gain remote access to the casino's security cameras, then used the camera feeds to spy on a gaming area and provide a single high-stakes gambler with signals directing him how to bet.
The gambler was kicked out of a villa at the casino and has since returned to his home country, while a VIP services manager who was assigned to look after the gambler has been fired.
A Crown spokesman told Buttler that Crown believes it's "in a good position to recover a significant portion of the amount involved in the scam."
ABC News' Simon Lauder reports that gambling security consultant Barron Stringfellow said the gambler appears to have accessed the casino's security systems along with an accomplice. "Then, though a wireless transmission to his ear during his eight hands of play, he was told exactly what plays would be beneficial to make. ... If casinos would monitor for wireless transmissions, they would be able to thwart these plans at the outset," Stringfellow said.
