Former Las Vegas Casino Employee Says He Was Fired for Being “Too Thorough” in Flagging Suspicious Players

A former compliance officer at Resorts World Las Vegas, Preston Banks, has filed a lawsuit against the company, claiming he was fired after reporting suspicious financial activity involving a group of foreign gamblers to management. The case was reported by the Las Vegas Review-Journal.

Banks joined Resorts World in September 2022 and was responsible for ensuring the casino complied with financial regulations, including anti-money laundering rules. Before that, he spent roughly 16 years as a specialist at the U.S. Treasury’s Financial Crimes Enforcement Network (FinCEN).

Banks initially flagged a group of clients, most of them from Argentina, but the investigation later expanded to include an estimated 60 to 150 players from several countries. According to his lawsuit, the source of large sums of money used by some of the players could not be clearly explained.

The suspicious activity Banks reported included:

• Players betting on opposite outcomes of the same game
• Clients feeding money into slot machines, barely playing and then cashing out
• Players passing chips to one another
• Some clients leaving the casino with chips instead of cashing them in
• Other people paying off gambling debts on behalf of certain players

On September 2, 2025, Banks submitted a detailed report on the group to management. Nine days later, Resorts World banned 28 clients named in the report from the casino.

The company also referred the matter to the Clark County District Attorney’s Office in connection with efforts to collect up to $13 million in unpaid gambling debts from the players.

Eighteen days later, Banks was fired. He claims his dismissal was retaliation for pressing for greater scrutiny of the clients.

Resorts World denies the allegations and calls the lawsuit baseless. The court will now determine whether Banks was fired in retaliation for raising concerns about suspicious activity.
