Las Vegas Scandal: Former Compliance Director Sues Resorts World for Retaliation

The Las Vegas gaming industry is facing a significant legal challenge as a former top compliance official takes his former employer to court. Preston Banks, who served as a regulatory specialist at the U.S. Treasury’s Financial Crimes Enforcement Network (FinCEN) for nearly 16 years, filed a federal complaint on September 14, 2026. He alleges that Resorts World Las Vegas fired him as an act of retaliation after he blew the whistle on suspicious activities involving a group of international high rollers. The lawsuit, filed in U.S. District Court, claims wrongful termination and whistleblower retaliation under the Anti-Money Laundering Act of 2020.

According to the legal filing, Banks identified what he called the Argentina Scheme shortly after joining the property in September 2022. He alleges that a group of gamblers, primarily from Argentina, grew to include between 60 and 150 individuals from countries such as Mexico, Italy, and Spain. Banks claims that the sources of funds for these patrons could not be verified because the businesses listed on their credit applications were non-existent. Despite his repeated warnings and the filing of over 50 suspicious activity reports (SARs), Banks alleges that his supervisors repeatedly minimized these concerns.

Numbers and facts

The scale of the alleged fraud is immense. The complaint states that the casino eventually barred 28 patrons and referred between $12 million and $13 million in unpaid casino credits to the Clark County District Attorney’s Office for collection. Banks is seeking reinstatement or front pay, double back pay with interest, and punitive damages. One of the most controversial claims in the lawsuit involves Al Meranto, the executive vice president of casino operations, who allegedly characterized the suspicious behavior as cultural during a meeting in 2025.

Banks was dismissed on September 29, 2025. He claims he was told the termination was related to the very illegal gambling scheme he had detected and reported. Furthermore, the lawsuit alleges that a version of Banks’s internal report shown to Nevada Gaming Control Board agents in March 2026 was scrubbed of critical details, including the cultural remark and information about controversial third-party payment exceptions.

Background

Resorts World Las Vegas has already been under regulatory scrutiny. In March 2025, the Nevada Gaming Commission approved a $10.5 million settlement with the resort over separate allegations of unsuitable methods of operation tied to illegal bookmaking. This context adds weight to Banks's claims that the property struggled with internal compliance and oversight. Banks has also filed complaints with OSHA and the Justice Department’s Corporate Whistleblower Awards Pilot Program, though rulings are still pending.

Why it matters for German players

For players in Germany, this case serves as a reminder of why the strict regulations under the Interstate Treaty on Gambling 2021 (GlüStV 2021) are in place. In the German market, the GGL (Joint Gambling Authority of the States) enforces rigorous controls that make the kind of massive credit fraud alleged in Las Vegas virtually impossible. The monthly deposit limit of 1,000 euros and the 1 euro stake limit on virtual slots are designed specifically to prevent money laundering and massive player debt.

German players are protected by the LUGAS central database, which monitors cross-operator limits. Unlike the situation described by Banks, where over 100 individuals could allegedly operate a coordinated scheme for years, the German system is built on automated transparency. Playing at a GGL-licensed casino ensures that the operator is subject to German AML laws, where compliance is a mandatory legal standard rather than a discretionary operational choice.

What it means for GGL-licensed casinos

Licensed operators in Germany must maintain impeccable documentation to satisfy the GGL and the German AML Act (GwG). The Resorts World case illustrates the danger of a disconnect between operations and compliance departments. In Germany, the Compliance Officer holds a position of significant responsibility, and any interference with their reporting duties would lead to immediate regulatory intervention. For GGL-licensed casinos, the lesson is clear: robust internal controls and the protection of whistleblowers are not just ethical requirements but essential for maintaining a gambling license in a highly regulated European environment.
