A strange footage of tiny circular specks of white light flying at high altitude over London in broad daylight was uploaded on YouTube two days ago.
Against the clear blue sky, five of the UFOs are seen speeding in the same direction before disappearing behind a cloud.
A much larger glowing disc then emerges from behind the same cloud.
It hovers slowly in a tight circle as other small specks follow the path of the others — before vanishing back behind the cloud.
The mysterious “mother ship” then returns to view briefly before finally disappearing.
A small crowd gathered near the Radio 1 studio in Great Portland Street, West London, to watch the spectacle and film it on their mobiles.
