Metro Police Lt. Clint Nichols said the heist occurred around 9 a.m. MST at the Palace Station Hotel and Casino on Sahara Avenue when a suspect with a shotgun allegedly relieved the guard of four sacks of cash and fled in a waiting getaway car.
Initial reports set the loss at more than $1 million. However, investigators later revised the figure to $36,000 plus several checks that had been cashed, KLAS-TV, Las Vegas, reported.
Nichols said no shots were fired in the incident and told the Las Vegas Review-Journal that the guard did not have the opportunity to draw his weapon.
KLAS said a number of Palace Station security guards had been distracted at the time by a car fire in the hotel's garage. Police could not immediately say if the fire was related to the robbery.
