A hotel maid is being hailed for her role in preventing what police fear could have been a "Las Vegas style shooting" at the upcoming MLB All-Star Game in Denver, a report said Saturday.

The housekeeper tipped off cops after she found more than a dozen weapons and 1,000 rounds of ammunition at a hotel near Coors Field on Friday, according to ABC7 Denver.

The alarming discovery was made inside a room on the eighth floor of the Maven Hotel, just two blocks from the mile-high ballpark that is hosting the "Midsummer Classic" Tuesday, the station said.

Cops removed 16 long guns, body armor and ammo from the room, which had a balcony overlooking Denver's downtown, the outlet reported.

Three men and a woman were arrested and charged with weapons possessions in connection with the cache. Three of the suspects were previous offenders, and three of them also were charged with intent to distribute drugs, the report said.

One suspect, a recent divorcee, had posted a cryptic Facebook message saying he would "go out in a big way," sources told the station.

"The investigation and arrests were the result of a tip from the public, serving as an excellent example of the critical role the community plays in public safety," police said in a statement Saturday night.

In 2017, a gunman opened fire from the balcony of a Paradise, Nevada, hotel during a music festival, killing 59 people and injuring hundreds more. It was the largest mass shooting in US history.
