London, September 28 Scientists have got hold of incredible new footage that could shows a mysterious monster lurking beneath one of the deepest lakes in the British Isles, which is unlike any creature ever seen.

According to a report in The Sun, Jonathan Downes spotted the "creature" thrashing around in one of the Lakes of Killarney in County Kerry, Ireland, while on holiday.

His eerie sighting was in the Upper Lake one of three interlinked lakes that make up the area.

The mystery comes just a few years after bizarre unexplained sonar recordings showing a large body were made in the adjoining Muckross Lake.

Along with his wife and friends who also had cameras, Downes, from Crediton, Devon, managed to capture shapes moving across part of the lake.

Downes, who is director at the Centre for Fortean Zoology, said that he had heard of the sonar reading before visiting the lake, but was "ridiculously" lucky to see anything.

"What we saw was a thing about nine to 10ft long. I'd love to say I saw long necks and humps and things but I didn't," he said.

Downes, who studies cryptozoology - which investigates unknown species of animals, described seeing what he see described as appearing to be "a long thin eel-like creature appearing about 10ft long".

"I believe it must be a large eel. It was a pale colour. What I saw didn't actually really come out on the picture as well," he said. (ANI)
