The incident occurred at the Walmart store at 7200 Arroyo Crossings at around 8:20 p.m. on Saturday evening local time, KLAS reported.

Officer Aden OcampoGomez, a spokesman for the Las Vegas Metropolitan Police Department, said the suspect walked into the store wearing a hazmat suit. He said 13 people in the store came into contact with the “clear liquid” the suspect was spraying — but none of them were injured or showed any symptoms, the Las Vegas Review-Journal reported.

“There was an individual that came into the store. He dressed in hazmat suit and started spraying certain items within the store,” OcampoGomez told reporters outside the store.

“At this point, we know that approximately 13 people came in contact with this substance that was being sprayed. None of these individuals have shown any signs or symptoms and nobody has been transported [to hospital] at this time.”

A witness in the store told KLAS that she called 911 after the man started spraying people and items including fresh food.

“He had some clear liquid in it with the painter’s tape, something written on it,” Zandra Calma said. “He was just spraying unnecessary things and peoples’ personal spaces, on conveyor belts, and worst of all, by the fresh foods.”

OcampoGomez added that the suspect left the store before authorities arrived — but someone in the store had followed him to his vehicle and got his license plate. As a result, officers were able to track down the suspect, who has not been identified, and take him into custody.

The spokesman said that it was not clear what the substance was, but that the matter is under investigation. “We take these threats very seriously,” he said.

He also said there was no danger to the community and also urged people to not panic buy items due to the COVID-19 pandemic.

“One of the things we want to urge the public is that we know there’s a difficult time going on with the world right now, but there is no reason for you guys to be going into the stores late at night and hoarding some of the supplies, due to the fact that there are plenty of supplies left in the stores at this point,” he said.

It was not immediately clear what charges the suspect would be facing. The police department has been contacted for additional comment.

Walmart employees voluntarily evacuated the store due to the suspect’s actions, KSNV reported. Newsweek has contacted Walmart and the Las Vegas Fire Department for comment.
