A UFO has been captured hovering over a San Diego motorway, a driver has bizarrely claimed.

The clip, which was captured last week in downtown San Diego, California, US, has left thousands of conspiracists making wild claims.

Nene Angulo captured the footage from his windscreen as he drove down the motorway.

In the distance, a round white object can be seen aimlessly hovering in the clear sky.

As Nene drives on, a smaller white object attached to its underside becomes visible.

He said: "Can you see that s**t? It looks like a big space station.

"But it's just floating in the sky, not moving at all."
