It is back to business as usual for the Red Rock Casino Wednesday.

It was a different scene Tuesday, when emergency crews were called out to the Red Rock Casino to handle a hazmat situation.

Metro says someone had left a pillowcase filled with illegal drugs in a parking lot.

When it was brought to the security office, at least five people became sick.

They are expected to be ok.

Police think the drugs mixed together, and that the workers were hit with the resulting gas when they opened the pillowcase.
