Attention Shipley... you are not alone. Could this photograph be evidence that alien intelligences from the far reaches of space have been visiting the Bradford district?

Emil Ziemczonek thinks it just might be. He snapped this shot of the skyline of the town on Sunday morning and when he looked at it later was shocked to see the distinctive saucer-shaped object above Shipley, to the left of the photograph.

Emil, 24, who works at the Denso Marston manufacturing plant, was travelling from Wrose back home to Rosebery Avenue in Shipley when he decided to take some pictures on his phone of the surrounding landscape.

He said: “I had a friend coming to visit from London and I wanted to show him the beautiful views. It was only when I got home and looked through the pictures that I saw the shape.

“I immediately thought that it looked like some sort of spaceship. I think it must have come from Space because it looks so very strange.”

He added that he hadn’t noticed anything in the sky as he snapped the pictures, at just after 10am on Sunday, because “it must have been flying very quickly”.

According to the website, which documents various UFO sightings and sorts them into different categories and shapes, the mystery object photographed by Emil could fall into one of the most common categories of alleged alien spacecraft.

The site shows pictures similar to the one taken by Emil and says: “Of all known craft, the domed disc is perhaps the most instantly recognizable, and has been portrayed countless times in the media, but in reality the shiny silver disc so often represented is but one of its many variants.

Emil said: “It definitely wasn’t a cloud. It’s mystery. It looks very crazy. I’ve shown it to a lot of people and they are as puzzled as I am.”
