A mysterious object shaped like a doughnut has sparked a conspiracy frenzy after being filmed soaring over Brooklyn in New York City in the US.
The footage was taken by a dog walker on an early morning stroll in the US city.
In the clip, a black UFO hurtles across the sky while seemingly rocking back and forth by the wind.
It appears to be a perfect doughnut shape, leading the man to claim it is like “a flying frisbee”.
The encounter happened on Saturday and was first shared to sightings website MUFON, before emerging on several conspiracy sites on YouTube including Tales From Out There.
In his description, the cameraman said: “As I glared at the moon for a bit, I saw this flat, black, disc-shaped doughnut appear from over the houses across the street so I immediately took out my phone and started to record it.
“Got about two minutes on film and went online seeking disc-shaped drones… nothing resembled what I saw and what you’re seeing in my video.
“Then I tried searching flat doughnut-shaped UFOs and found a bunch of these objects like the one in my video.
“I can’t say for sure what it is, but it’s definitely unidentifiable.
“I hope the public can help me figure out what I saw.”
Many of the viewers were equally flummoxed by the sight. One wrote: “That’s crazy back and forth stuff, no drone.”
Another added: “If real, that’s a harbinger.”
But others were less convinced, with suggestions ranging from the object being nothing more than a balloon to simply being a drone.
It is not the first time a supposed UFO has been spotted in the Big Apple.
Last month, a huge triangular object was captured on video gliding through the sky.
