Nazca Tomb: Steve Mera (pictured) was told that metal allegedly found at Roswell was in the tomb.
It is said to be similar to a type of aluminium claimed to have been found near the alleged Roswell flying saucer crash site in New Mexico that was said could repair itself if bent.
Yesterday, Express.co.uk revealed a new twist in the mystery – after claims emerged live beings were seen in the tunnels where more than 20 mummified bodies were allegedly found.
Historians and many UFO researchers have branded the three-fingered mummies an audacious hoax.
However, UK-based UFO investigators Steve Mera and Barry Fitzgerald travelled to Peru to try to establish if they could be genuine.
They spoke to members of the Inkari Institute, an archaeological research team in Cusco, Peru, which was allegedly handed the bodies by blackmarket tomb raiders.
The pair have made a video documentary charting their adventure.
Nazca Tomb: Steve Mera inspects ‘alien mummies’ at a secret location in Peru.
Mr Mera spoke to camera after a meeting with the institute which included its president Thierry Jamin.
He said: “There is an international racket where people might be buying artefacts illegally.
“The more we get into this, the bigger the hole is getting.
“Terry (Jamin) is battling to keep artefacts in the country, he thinks it is important they stay in Peru.
“Some of these things are getting out there, and one of these things was apparently just like the Roswell footage, sorry the Roswell incident.
“This foil that unfolds itself – some of this was found and sold for only $8,000 to someone in Asia.
The Roswell flying saucer mystery has been at the heart of the UFO scene.
In July 1947 the US military sensationally announced in a press release it had found the remains of a crashed flying saucer in the desert nearby.
But the following day it retracted the statement, saying it was in fact a damaged US Air Force air balloon.
Witnesses later came forward to say there had been alien bodies within the “crashed craft”, which along with the wreckage were then taken to a mysterious top-secret military base.
All the confusion means it is one of the world’s biggest conspiracy theories.
However, since then people came forward to say they saw metal from the crash site which unfolded itself if bent.
Yet, to date no one has ever produced any of the metal.
Mr Mera and Mr Fitzgerald were told during the interview the area around the tomb had a “strong electromagnetic field”.
Mr Fitzgerald said: “Our heads were left spinning from what we were told and we were promised a lot more information.”
Some of these things are getting out there, and one of these things was apparently just like the Roswell incident.
Gaia.com, the paranormal website behind the outlandish claims, says that at least five mummified aliens have been found buried in Nazca, Peru.
The website has released a five videos about the “discoveries,” and insists a genuine investigation is underway.
The latest disclosure came after scientists and the Peruvian World Congress on Mummy Studies released statements saying they believed the creatures were hoaxes.
Mexican journalist Jamie Maussan, who is leading the probe in the Gaia.com videos, has previously investigated a series of alleged alien body discoveries which turned out to be hoaxes.
Many ufologists believe the Gaia.com films are promoting a massive hoax.
Nigel Watson, author of the UFO Investigations Manual said they were “plaster of Paris fakes”.
Express.co.uk has asked Gaia.com and Mr Maussan for details about the discoveries.
We asked for the location, who found them, whether it was part on an official dig, and if there were any pictures of the discovery.
Mr Maussan said at an earlier press conference about the discovery that the mummified burial of the bodies suggests they once coexisted with humans.
He said: “These mummies were buried in human tombs, in sacred places.
“This means that they had coexisted with our ancestors, were not enemies and had, to a certain extent, a degree of respect between both races or cultures.”
Gaia.com claim tests show the bones to be 1,700 years old, and the beings had three fingers and elongated skulls.
For years there have been claims by alien conspiracy theorists that aliens visited our ancestors and helped them build great structures like the Pyramids of Giza and Stonehenge.
In a press release, the pair said: “Recently, the internet exploded with images of newly discovered mummies, discovered in the region of Nazca, Peru.
“This is not the first time such earth shaking discoveries have been found, only to turn out to have a more mundane explanation.
“Could these recent findings be what we have been waiting for?
“We have recently returned from Peru after conducting a painstaking and thorough investigation that encompasses physical examinations of the bodies, scrutinising X-rays and scans, reviewing medical conclusions and being cast into the murky depths of the illegal black market.”
