A Las Vegas regular is accusing one of the Strip's glitziest casinos of turning a VIP night into a financial nightmare. Michael Duke Thomson, a 64-year-old attorney and longtime Aria patron, has sued Aria Resort & Casino and parent company MGM Resorts after a January 2024 stay allegedly ended with him waking up handcuffed in casino security and on the hook for roughly $75,000 in markers, as reported by The Independent.
In a federal complaint, Thomson says he was "surreptitiously drugged" while gambling in Aria's high-limit rooms, leaving him incapable of understanding his actions as the markers were issued. He also alleges casino staff failed to step in as he continued to gamble. Thomson is asking a judge to void the disputed credit instruments and send his claims for damages to a jury, according to The Independent.
Thomson filed the complaint on Dec. 11 in the U.S. District Court for the District of Nevada, according to a docket hosted by Justia Dockets & Filings. The filing names Aria Resort & Casino, LLC and MGM Resorts International as defendants, includes a demand for a jury trial, and seeks relief that would rescind the markers.
Thomson's Version Of A Lost Night In The High-Limit Room
According to the complaint, Thomson's last clear memory on Jan. 23, 2024, was around midnight as he left Aria's high-limit blackjack room with "a few thousand dollars" in chips after taking a single $10,000 marker that he says he repaid at the table. After that, he claims, the lights go out.
Thomson says he awoke the next morning in a casino security holding pen, handcuffed, and was told by a VIP host that he had eight outstanding markers totaling about $75,000. He alleges he has no memory of signing or using those markers because he had been drugged, as reported by The Independent.
The complaint alleges the markers were issued between roughly 3 a.m. and 9 a.m. on Jan. 24 and that the signatures on most of them "only loosely resemble" Thomson's usual signature. About three months later, his bank returned five of the instruments as "Not Authorized" and marked three as "NSF." Aria then referred the matter to the Clark County District Attorney's Bad Check Unit, which led to criminal charges, according to Casino.org, which reviewed the filing and related court records.
Criminal Case, Payout, And Dismissal
Local records and reporting show Clark County charged Thomson in November 2024 with drawing and passing a check with intent to defraud and theft, and set his bail at $10,000. In his civil complaint, Thomson says he paid $15,480 to secure his release from custody and later paid off the contested Aria markers in order to relieve the pressure of the pending criminal case. The criminal case was dismissed in mid October, according to The Independent.
Responsible Gaming Rules And Casino Watchdogs
Nevada requires licensed gaming operators to maintain responsible gaming measures, including staff training, visible signage, and resources for patrons who may be in trouble. Casinos say they train employees to spot and assist impaired players.
MGM has publicly promoted a companywide program called GameSense as part of its responsible gaming efforts, according to MGM Resorts. Academic and regulatory experts have also emphasized that casino policies and frontline employee training are central to preventing exploitation of visibly impaired guests, per material from the UNLV International Center for Gaming Regulation.
What Thomson Wants The Court To Do
Thomson's lawsuit accuses Aria and MGM of negligence, unjust enrichment, and malicious prosecution. It asks the court to declare the disputed markers unenforceable, formally rescind them, and award damages at trial. The federal docket confirms the filing and jury demand, according to Justia Dockets & Filings.
Industry reporting notes that, as of Friday, MGM had not filed a response to the complaint or answered media requests for comment, according to Casino.org.
Whether this case nudges casinos to tighten how they monitor potentially impaired high-stakes players is an open question. For now, the lawsuit puts Aria's handling of an allegedly incapacitated guest under a microscope and asks a jury to decide whether the casino's staff and procedures met their legal obligations when the chips were really down.
