An unidentified Macau casino has been victimized by a con job involving the fraudulent winning of some HKD 24.4m (US $3.1m).

On Monday, Macau Judiciary Police announced that they had arrested one casino pit manager and three VIP gaming collaborators, aka junket associates, after receiving a report on Friday from an unspecified casino regarding a VIP gaming room fraud.

Police said the pit manager had stolen a deck of playing cards from the VIP room at which he worked. These cards were then apparently marked in a way that allowed the three other conspirators to identify the card values before they were turned face up. Police said they were still investigating the manner in which the cards were marked.

PJ spokesman Ho Chan Nam told GGRAsia that the scammers wagered a minimum of HKD 1m per hand, winning HKD 24.4m within about half an hour’s time. All the wagering was done with a single shoe of cards.
