The Las Vegas UFO mystery has deepened – as police installed high-tech cameras outside the home where residents reported seeing ’10ft aliens with large shiny eyes’ in their backyard

Doug Poppa, a former police officer who has been following the story of the mysterious object falling from the sky, said it baffled him why the Las Vegas Metro Police Department placed surveillance cameras outside.

He interviewed the family who made the call – and they told him that the cops installed the camera to ‘protect’ them from UFO fanatics who might bother them.

Despite being skeptical, Poppa, who is a podcaster, said he now believes the family is somewhat credible.

A Vegas officer’s body camera picked up the object at about 11:50pm on April 30, after a resident reported something ‘100 percent not human’ on their property, local TV channel 8 News Now reported.

The footage shows a bright blue ball of light traveling through the dark sky at speed.

Approximately 39 minutes after the first call, another resident contacted 911, saying that there were two unknown entities in his backyard after he saw an object fall from the sky.

‘There’s like an 8-foot person beside it and another one is inside us [sic] and it has big eyes and it’s looking at us — and it’s still there,’ the homeowner told police in audio obtained by the TV channel.

Mr Poppa wrote on Twitter, along with an image of the supposed cameras: ‘THE VIDEO CAMERA SURVEILLANCE SYSTEM WITH THE WIRELESS TRANSMISSION LINK THAT I RECORDED AT THE HOME ON MAY 19, MUST HAVE BEEN A MIRAGE OR A FIGMENT OF MY IMAGINATION IF THE LAS VEGAS METRO POLICE ARE TO BE BELIEVED.

‘NICE INSTALL TASS (TECHNICAL AND SURVEILLANCE SQUAD).’

He told NYPost: ‘The mother told me they came out there and put up the cameras, supposedly to protect the family from people coming to bother them about the UFO.

‘But I can tell you right now. Cops don’t come out and put up expensive video equipment up like that — and they certainly wouldn’t for someone calling in a report about a UFO.’

During the initial 911 phone call about the alleged UFO and alien sighting, the caller said: ‘In my backyard. I swear to God this is not a joke, this is actually — we’re terrified.

‘They’re very large. They’re like 8 foot, 9 feet, 10 foot. They look like aliens to us. Big eyes. They have big eyes. Like, I can’t explain it. And big mouth. They’re shiny eyes and they’re not human. They’re 100 percent not human,’ he claimed.

The responding officers expressed their trepidation at the odd events.

‘I’m so nervous right now,’ one officer can be heard telling his partner.

‘I have butterflies, bro — saw a shooting star and now these people say there’s aliens in their backyard.’

‘I don’t believe in it but what I saw right now, I do believe in it,’ one of the reported witnesses said to police.

The area of the alleged sighting was searched, and the witnesses interviewed, but no new information was found.

The Vegas investigations come after a Pentagon whistleblower who claims the US has run a top-secret UFO retrieval program for decades said some of the ‘non-human intelligences’ discovered are malevolent and have even killed humans.

David Grusch served 14 years in the Air Force, where he says he was told about the program by others who were involved.

Grusch, 36, is a decorated Afghanistan combat officer who went on to work for the National Geospatial-Intelligence Agency and the National Reconnaissance Office.

His role was to act as the NRO’s representative when dealing with the Unidentified Aerial Phenomena Task Force. The task force was specifically set up to investigate UFOs.

Over the last week, he has gone public with what he says it entailed, telling NewsNation about how the US is in an arms race with Russia and China to understand extra-terrestrial life.

In his most recent comments, he said the ‘non human’ intelligences have acted with malevolence – and even killed some humans.

‘I think the logical fallacy there is because they’re advanced, they’re kind. We’ll never really understand their full intent and that’s because we’re not them.

‘But I think what appears to be malevolent activity has happened.

‘That’s based on nuclear site probing activities and witness testimony.

‘While I can’t get into the specifics because that would reveal certain US classified operations, I was briefed by a few individuals on the program that there were malevolent events like that,’ he said, when asked specifically if any had killed humans.

Grusch also made the astonishing claim that the US government would do anything to protect the secret – including killing people.

‘At the very least, I saw substantive evidence that white-collar crime was committed…unfortunately.

‘I’ve heard some really un-American things I don’t want to repeat right now,’ he said.

Grusch filed his report in July last year. At the time, the Intelligence Community Inspector General called the complaint ‘urgent and credible.’

‘There is a sophisticated disinformation campaign targeting the U.S. populace which is extremely unethical and immoral,’ he said, accusing the US government of lying to the public for ‘decades’.

‘We are most definitely not alone,’ he said, adding that ‘quite a number’ of aircraft have been discovered.

The Pentagon denied having any knowledge of the program described by Grusch last week, but stated it would follow ongoing investigations into his claims ‘wherever they lead’.

The House Oversight Committee also commented it will investigate his claims.
