UFO captured on a police helicopter in South Wales

Found this footage last night I had saved from an old article thought it was interesting.

Footage from the South Wales police force’s heat-seeking helicopter camera shows a spherical object bobbing around in the centre of the screen. Confused police said the mystery object was flying against the wind and was undetected by air traffic control at around 9.30pm. None of the crew could come up with an explanation of what it was and the team tweeted it with an allen emoji and the question: ‘Any suggestion??’
