A woman claims to have spotted the elusive Loch Ness Monster, witnessing the mythical beast "rolling" and "spinning" on the Scottish lake's surface during a weekend excursion.

In a thrilling account that has stirred one of the most intense Loch Ness Monster hunts in recent memory, Chie Kelly, 51, a translator, reported an encounter with a serpentine figure while photographing her husband Scott by the iconic waterside.

She detailed the moment the creature performed a languid spin on Loch Ness's surface before diving into the depths, vanishing from sight.

Chie vividly remembered spotting the anomaly approximately 100 meters distant, cruising at a "steady speed" from right to left, concluding its display around 200 meters from the shoreline.

"We had lunch in the Dores Inn and then started walking around. I was just taking pictures with my Cannon camera of Scott and our daughter Alisa, who was then five, when about 200 meters from the shore, moving right to left at a steady speed was this creature. It was spinning and rolling at times. We never saw a head or neck," she said.

After observing it for several minutes, the creature disappeared, not to be seen again. Initially, the Japan-born translator speculated it could be an otter, two otters, or even a seal, but the lack of a visible head and the absence of resurfacing for air quickly ruled out those theories.

"It was making this strange movement on the surface. We did not hear any sound. There were these strange shapes below the surface. I could not make out any colours - the water was dark.

"I could not accurately assess its length, but the two parts that were visible were less then two metres long together. I don't know what it was but it was definitely a creature - an animal. At the time I did not want to face public ridicule by making the photographs public."

This incident transpired merely nine days subsequent to father-of-four Steve Valentine's alleged observation of Nessie. While aboard a vessel with his progeny, Steve said: "I spotted this black shape, about 200 metres away, near Urquhart Castle,".

He recalls feeling compelled to capture the image. Unfortunately, one of his children leapt onto his lap, causing the boat to swivel.

The photograph, however, was sufficient to startle the driver. Steve elaborates on his experience, "I am quite open-minded, I was genuinely shocked."
