London - A giant wind turbine in Britain has been wrecked after probably being hit by an Unidentified Flying Object (UFO), the Sun newspaper reported Thursday.

Locals living near the wind farm in Lincolnshire, in the east of England, reported seeing "strange lights" streaking towards the tall generator during the night on Sunday.

One of its three giant blades came off completely and another was left twisted and severely damaged, said the Sun.

While UFO experts said they were "excited" by the incident, investigators told the BBC that they were working at other possible theories to explain the "unique incident."

These included lightning, ice falling from an aircraft and material fatigue.

Dorothy Willows, who lives near the town of Louth where the incident took place, told the Sun: "The lights were moving across the sky towards the wind farm. Then I saw a low flying object. It was skimming across the sky towards the turbines."

Another witness reported a "giant explosion in the air."

John Harrison, a local man, had yet another observation. He reported seeing a "massive ball of light with tentacles going right down to the ground" over the wind farm.

"It was huge. With the tentacles it looked just like an octopus," Harrison told the Sun.

The Ministry of Defence in London said: "Unless there is evidence of a potential threat, there is no attempt to identify the nature of each sighting." (dpa)
