State police have arrested two Rivers Casino employees after what investigators are calling a “complex cheatingconspiracy” that took place at a Roulette table.

State police said Robin Schnepp, a table games dealer, and supervisor Anthony Laush helped at least two players cheat on several occasions and win thousands of dollars.

Investigators were tipped off by an anonymous letter sent to Rivers Casino earlier this year about Interblock Roulette, which requires the dealer to manually spin the ball in the opposite direction of the wheel. When that does not happen, sensors do not identify that the wheel has been spun, allowing players to continue to place bets, even after the ball lands on a number and the outcome has been determined.
