UFO Captured on Helicopter Thermal Imaging

Footage from a heat-seeking helicopter camera shows a spherical object - It was filmed while officers were flying 1,000ft over the Bristol Channel.

They don't know what it is and have taken to Twitter to ask for suggestions.

Police have been baffled after a UFO appeared on one of their cameras.

Confused police said the mystery object was flying against the wind and was undetected by air traffic control at about 9.30 pm on Saturday.

Thermal cameras captured the object - which could not be seen with the normal eye.
