Owners of the M Resort owe the City of Henderson millions of dollars in unpaid fees.
The Las Vegas Review-Journal reports M Resort owners owe Henderson roughly $15 million from an agreement signed more than a decade ago.
According to the 2008 agreement, the owners were supposed to repay the city nearly $8 million for water and sewer infrastructure and $7 million to build a pending fire station.
Despite annual reviews of the development agreement, city officials missed the payments until last year, when an internal audit brought it to light.
Penn National Gaming took control of the M Resort in October 2011.
Henderson City Attorney Josh Reid said the payment was deferred for several years but triggered in 2012 once the new owners installed a permanent tent structure to house concerts and conventions.
