POLICE in UFO mecca Roswell are on the hunt for a flying saucer after all trace of it was lost, following reports of a "crash".
The Roswell Police Department sent out a plea on Facebook this week with the title: "Be on the lookout: Missing spaceship."
Three mystery beings have also been caught on camera.
Unfortunately for those seeking confirmation of an alien visitation on Earth, cracking this case will not lead to the closure they crave.
In fact the saucer in question is not an unidentified flying object (UFO) but was, in fact, an identified fixed object (IFD).
The IFD in question was a mock-up flying saucer on the outside of the Roswell UFO Museum.
Ever since July 1947, when the US Air Force released a statement saying it had found the remains of a crashed unknown craft, the remote New Mexico town has been at the heart of UFO mythology and conspiracy theory.
For the following day, the same department issued a statement saying it was wrong, and it had in fact been a weather balloon.
From then on the UFO legend was born along with conspiracies of how the military recovered a crashed space craft and the remains of its alien pilots.
The current mystery centres on a flying saucer which was on a corner of a building dedicated to the town's notoriety in alien circles.
A storm this winter knock it off the side of the building - technically making it a flying saucer crash.
Staff stored it under an awning behind the museum, but the landmark has now gone.
Thieves are believed to have made off with the fake craft at the weekend.
CCTV footage shows three human being suspects in a red pick-up truck carrying the saucer off, said officers.
A spokesman said: "It should be hard to hide or sell the UFO. It's made from fiberglass, metal and stainless steel and is wider than the truck bed it was spirited away in. It had been repaired after its winter storm adventure and was just waiting to be reinstalled on the corner of the building."
Facebook commenters have given the police some helpful suggestions, while others have taken the opportunitry to turn the tables in the Roswell myth.
One person recommends contacting NORAD, the organisation tasked with the "detection, validation, and warning of attack against North America whether by aircraft, missiles, or space vehicles."
Another Facebook poster said "the aliens from the 1947 crash may have come back for their spaceship" while another joked the missing prop "was not a flying saucer, but actually a weather balloon."
Residents hopey, the case will be solved with the return of the UFO in time for the town's annual alien festival when thousands of believers converge on the town in July.
