Nevada gambling regulators fined a hotel-casino in Laughlin a record $500,000 in a settlement with the state Gaming Control Board stemming from a pair of incidents involving security officers who roughed up a patron and a resort employee nearly two years ago. The Nevada Gaming Commission unanimously approved the settlement Thursday with Don Laughlin’s Riverside Resort, which fired four of the security officers and reassigned the fifth to a different job following the separate incidents in 2022, the Las Vegas Review-Journal reported. The commission said the fine was the highest ever assessed for incidents of their kind.
