Watch police helicopter footage which captures UFO flying over Bristol Channel
A police helicopter may have caught sight of a UFO flying over the Bristol Channel.
The invisible object, which could not be seen with the normal eye, was captured by thermal cameras.
The mysterious footage was filmed by the South Wales police helicopter while they were flying 1,000ft over the Bristol Channel at around 9.30pm on Saturday, September 24.
With none of the crew being able to come up with an explanation of what it was, the team tweeted it out with an alien emoji stating: "Any suggestion??"
Some have suggested it could be a balloon or a Chinese lantern, but police have ruled out both ideas because of the heat and movement.

The mystery craft was said to be flying against the winds at the time and was said to be undetected by air traffic control.
"It's difficult to judge the size but we filmed it for just over seven minutes," the police twitter account stated.
