Strange flashing lights spotted in the sky during a power cut have prompted a spate of UFO sightings.

The Herald has received several calls from residents who claim to have seen glowing "boomerang" and "cigar shaped" objects floating in the sky over Talysarn during the early hours of Monday morning.

The sightings occurred during a power cut which plunged the village and the surrounding area into total darkness for an hour.

One caller, who did not want to be named, said: "I sleep very badly and was on my way to the bathroom when I opened the curtains and saw this blinding emerald green light. The whole village was pitch black so it obviously stood out. Also, one of the lights coming from it had a strobe type effect."

"It was the size of a car, had three lights on and was traveling at no faster than walking pace.

Another eyewitness said: "I was downstairs when I saw this flash of brilliant bright light from the window."

He said: "I looked out and saw this cigar shaped object filled with light floating in the sky. It was incredible. Judging by the way it moved it definitely wasn't an aeroplane or anything I'd seen before."

This isn't the first time that Talysarn has hit the headlines for being a UFO hotspot.

Richard Foxhall, from Talysarn, has written the only Welsh language book about UFO sightings. He was spurred on after his investigation into strange lights above Dyffryn Nantlle drew a blank.

In 1996 he saw a strange light above Tal-y-Mignedd mountain which he reported to the Ministry of Defence.

The MoD, Civil Aviation Authority, North Wales Police and CIA had no record of flights in the area at that time.

Talysarn councillor Dilwyn Lloyd said such sightings were not uncommon.

"I have had a couple of calls from people in the village who said they saw similar things in the sky during the early hours of Monday morning," he said.

"I've spoken to someone who was taking his dog for a walk near Drws-y-Coed in Nantlle one night and saw orange, red and emerald green light in the sky. The next morning there were two military helicopters searching the area.

"It is very strange. Personally I have never seen anything but we would be naive to think we are the only life forms of all the planets in the universe.

"For the past couple of years there have been constant sighting in August.

"Why August? perhaps they're on their holidays and want to come to see the beautiful scenery we have here."

A spokesman for Scottish Power said: "Around 100 homes in the Cilgwyn area lost power at around 2.06am on Monday due to a high voltage cable fault. Engineers had to shut down the power supply to another 100 homes in the area in order to carry out repairs. The power was back on by around 3am.

"We would like to apologise to our customers for any inconvenience caused during this time."
