As if having a monster on the doorstep wasn’t enough, a tourist visiting Loch Ness claims he has photographic evidence of two UFOs flying over the famous lake.

Alan Betts was on holiday with his wife Anna and her parents, when the group captured the image, seen above, of two mysterious disc-shaped objects flying over the famous freshwater loch in the Scottish Highlands.

The picture was taken by Anna's mum, Tatiana, but it wasn't until Alan and his wife returned to their home in York and started looking through their holiday snaps that the bewildered couple discovered the strange white shapes hovering over the loch.

They were staying at a holiday cottage near Urquhart Castle when the shot was taken.

Alan said he was usually very sceptical about UFOs but couldn't offer an explanation for the spooky picture.

"Our Akita dog, Yuka, was strangely unsettled that night. He never barks but I remember we were laughing at the time saying that he'd seen Nessie because he was looking outside from the cottage window and barking at the sky,” said Alan.

“We couldn't see anything at that time though.

"We had been very lucky with the weather and were stunned with the view we had, it was almost constant sunshine but then that day, when we got back to the cottage after a day of sightseeing, the weather suddenly changed.

"We'd not seen it change that quickly before, which is why my mother-in-law went outside to take a general landscape picture.

"After the holiday we were looking through the pictures on our PC, as they were taken on a digital camera.

"On the PC screen the resolution was better and it was only then we saw the objects, when we zoomed in we were in shock.

"I can't offer any logical explanation, I am probably one of the most sceptical people you could find about things like this but I just can't explain what it is.

“I know what it looks like though.

"We showed the pictures to Anna's parents who were as shocked as us and her dad is probably more sceptical than me."
