Hertfordshire Police have released this audio of a local man who called 999 (the UK's version of 911) after seeing what he believed to be a UFO.

Moments later, the man was forced to phone back when it occurred to him that the UFO was in fact the moon.

Hertfordshire Police have released a statement saying that they released the video to show how time can be wasted around Halloween with bogus calls.
