The city of Sao Paolo is abuzz after amateur footage showing what appears to be an unidentified flying object appeared moving through the clouds.

he grey, saucer-shaped object could be seen for nearly a minute before suddenly disappearing in a bright flash of light.

The spectacle is followed by two more mysterious bursts of light.

Brazilian television channel G1 obtained the footage from some motorists who spotted the object near the town of Agudos.

The motorists, who the channel did not identify, said they rushed from their car to film the object with a hand-held camera.

G1 reports that the two camera-operators said that the earth shook just as the two blasts of light appeared – a fact that was corroborated by other people nearby at the time.

Yet no seismic activity has been reported in the area, the nearest tremors occurring south, in Chile.

Philip Cavaca, an expert in video editing, told G1 that the two that reported the sighting are nothing more than expert hoaxers.

‘It can be seen in one frame. When the truck goes by, you can tell that the UFO was moved, which is unnoticeable to the naked eye,’ Cavaca said.

By freezing the image you can see the exact frame in which the so-called UFO alters, Cavaca claimed.
