Astonishing new footage shows a mysterious creature shooting through the waters of Loch Ness 'like a torpedo'.
The sighting was made using a webcam maintained by Visit Inverness Loch Ness (VILN) at Shoreland Lodges, near Fort Augustus, on the loch's southern shore.
Though its actual size might have been hidden underwater, the enthusiast calculated that the portion of the creature above the surface measured at least six feet in length.
He said: "Looking across the calm conditions of Loch Ness via webcam I suddenly captured a strange disturbance about three-quarters of a mile away.
"Something rose up out of the loch, that initially looked like a large fish jumping, but then it moved like a torpedo, causing a significant wake.
"My heart jumped. I said to myself, "This is nothing ordinary - on the contrary, this is something you don't see every day".'
Even though Mr. O'Faodhagain frequently logs on from his house in County Donegal, Ireland, to watch the water, the sighting seemed unusual to him.
Given the lack of a clear explanation for the creature's "electrifying pace," he believes the Loch Ness Monster may be the culprit.
He said: "It is very unusual and, because it is Loch Ness, you begin to dream and contemplate, is it something else that is causing the disturbance?
"It's difficult as nobody is sure what type of species Nessie is. As you can see from the footage, it is very striking."
He added: "The speed of the object has no comparison to a bird taking off.
"You wouldn't see the movement of their feet at five yards, never mind three-quarters of a mile away on a webcam.
"Seals and otters do not behave like this, and the object moves too straight and direct to be considered an eel - even a giant one."
Mr. O'Faodhagain can offer an explanation for her abrupt speed if it is Nessie.
"I would say feeding would cause a creature to behave in such a manner - feeding for fish, close to the surface of the loch," Mr. O'Faodhagain explained.
The Loch Ness Monster remains a mystery, with three sightings reported in August, sparking excitement among Nessie hunters.
The first sighting, in May 1933, fueled the modern fascination with the creature.
Inverness Courier reported a local couple witnessing an enormous animal rolling and plunging on the surface.
A picture taken by London physician Robert Kenneth Wilson in the following year captured the world's attention, showing the beast rearing its head out of the water.
Chris Spurling, one of the participants, revealed on his deathbed that the pictures were staged, with a monster model on a toy submarine.
