London, Oct 20 : A 'flying saucer' photographed in daylight above Dudley in the West Midlands has been hailed as 'one of the most convincing pieces of evidence about aliens ever'.
The photo was taken by a 57-year-old nanny on a day out last April.
The startled visitor to Dudley Castle then sent it to a police detective who collects UFO sightings.
"It's a very intriguing photograph that was taken purely by chance," the Sun quoted DC Gary Heseltine, as saying.
"If it's genuine then it could be one of the most convincing pieces of evidence about aliens from the UK ever," he added.
DC Heseltine, of Wakefield, West Yorks, has now handed it over for study to a former US navy physicist who specialises in photo analysis.
The British Transport Police officer will reveal the findings at the UFO Data Magazine annual conference in Pontefract, West Yorks, on October 25.
