David DeMaison was apprehended by security officers Friday at the Las Vegas Strip hotel-casino. He then was arrested by Las Vegas Metro officers.

Among the charges he is facing is conveying false information concerning an act of terrorism, according to KTNV,  a local TV station. If convicted, DeMaison could face between two and 20 years in prison. He could also be ordered to pay a fine.

I have a nuclear weapon. I will kill everyone here,” DeMaison was heard saying.

He also allegedly said, “I will blow up the whole country,’ according to local TV station, KLAS.

Hotel security cameras recorded the alleged threats made by DeMaison. As a precaution, Metro officers notified Fusion Watch about the incident. The Southern Nevada Counter-Terrorism Center monitors terrorist risks in Las Vegas and elsewhere in Clark County.

Three-Plus Years Since Mandalay Bay Killings

Las Vegas is no stranger to threats or actual mass killings. On Oct. 1, 2017, Stephen Paddock, then 64, opened fire on those attending a music festival on the Strip.

Poised at a 32nd-floor suite in the MGM Resorts International-owned Mandalay Bay Resort and Casino, he killed 61 victims. More than 800 others were injured. Police never uncovered a motive and claimed the shooter fatally shot himself.

Airline-Linked Threat

In April, McCarran International Airport security beefed up after a man allegedly threatened to blow up planes and shoot people in Las Vegas. The threat came after he was informed by Frontier Airlines a carry-on fee would be charged for a piece of his luggage, Metro police said.

Andrew Greco, 52, who is believed to be from Stateline, Nev. was arrested on two charges: communicating a bomb threat and making a threat in an act of terrorism, the Las Vegas Review-Journal reported, citing court documents.

The airport saw increased patrols and federal law enforcement agencies were notified of his alleged threats as a precaution. Metro police alerted counterterrorism officials and the FBI.

He was staying at Las Vegas’ South Point Hotel Casino & Spa, the report said. From his room, he allegedly called Frontier customer service at least 11 times during a single night. He allegedly threatened to “kill people in Las Vegas or blow up an aircraft,” according to the police report.
