Police in Wales were called to investigate a mysterious flying saucer, only to discover it was the moon.

The moon was mistaken for a "bright, stationary" UFO which had been loitering for at least half an hour, by a confused local in South Wales who made a 999 call to the police.

Today officers released a transcript in order to highlight the time wasted by unnecessary 999 calls.

The bizzare conversation ran as follows:

Control: "South Wales Police, what's your emergency?"

Caller: "It's not really. I just need to inform you that across the mountain there's a bright stationary object."

Control: "Right."

Caller: "If you've got a couple of minutes perhaps you could find out what it is? It's been there at least half an hour and it's still there."

Control: "It's been there for half an hour. Right. Is it actually on the mountain or in the sky?"

Caller: "It's in the air."

Control: "I will send someone up there now to check it out."

Caller: "OK."

After the police patrol car arrives, the script reveals the exchange between the control room and the police officer sent to the scene.

Control: "Alpha Zulu 20, this object in the sky, did anyone have a look at it?"

Officer: "Yes, it's the moon. Over."

A police spokeswoman said: "This was a recent example of an inappropriate 999 call to South Wales Police.

"Yes, we can all see the comical side but calling 999 with an unnecessary non-emergency call could block a genuine call for vital seconds and put lives at risk."

Other bizarre calls cited by the police force included someone asking for help voting for Rhydian on The X-Factor and another requesting a pound coin for their supermarket trolley.
