Rumours of mutilated sheep have led a local UFO investigator to ask for information about a sighting in March.

Donald Cooper, from Skipton, read about Beryl Southwell's sighting of a UFO on Briggate in Silsden, in a Keighley News report.

Mrs Southwell said she had seen the large object with lights hovering outside her house at about 4am on March 13.

The Keighley area is renowned for recording high numbers of UFO sightings, and Mr Cooper investigates the phenomenon.

He says: "I would just like to hear from anybody else who saw this object. It is important to get as many witnesses together as possible to substantiate this sighting.

"Someone else must have seen it and I would urge them to come forward.

"I have heard some rumours that farmers have experienced sheep mutilation is the area recently.

"I want to hear from any farmers who have had any mutilations of their stock or strange experiences. It is possible that this could be connected to the sighting in March."

Mr Cooper cites a report from the Pontefract based group UFO 2000 that sheep and lamb mutilations near Cowling last year suggested extra terrestrial involvement.

Attributed to big cat activity at the time, the mutilations off the A6068 on Keighley Moor baffled local experts.

Over a period of five weeks sheep and lambs were discovered mutilated with a mixture of crude predator injuries and some very neat precise incisions and small holes in others.
