Photographer Alan McNamee, from Bridport, is convinced of the existence of the animal.
He has now assembled a team who are ready to respond to sightings as they are reported.
Alan saw the animal close up in 2004 - an experience he said was "scary". He said: "I was working late one night at home and I heard a noise. I went downstairs and looked outside, towards the fields at the back of my house, and I saw that the hedge was thrashing about.
"Then I saw a large cat with a badger in its mouth. "It leapt onto a bank and disappeared.
"It completely shook me up." Alan called the police who visited the scene immediately.
He said: "The police returned the next day to have a look at the area [in daylight] and they confirmed that they had found paw prints." Alan's interest has now been renewed after a series of new sightings, and he has contacted a team of experts, including a 'big cat' expert and a specialist vet, to help establish the truth. Alan said: "I'm hearing of several sightings a week. [The people who see it] are just people going about their normal business. "The last sighting was Friday evening [19 February 2010]. "A woman was driving over the A35 [between Bridport and
"I have also had land owners who have said they have seen it ."And all of those sightings are of a similar format. "It's farmers finding unusual footprints on their land, or sheep or cattle being attacked. "The animals have two punctures in their neck and their internal intestines are gone. "They have a broken back, there's no blood, and some have been dragged to the top of a tree. "But to drag a heavy sheep across a field for a 100 yards, over a fence and up a tree - that's not the work of a dog or a fox." Alan is now waiting for the next sighting, with the hope that he can get to the scene immediately and find enough evidence or remains that can be recorded and analysed. This needs to be carried out as quickly as possible after an animal attack as this is the key to gathering evidence which can determine what the creature is. "It's vital we get there within a few hours after a kill, to take photos, take DNA and look around for anything else." "Everyone says the same thing [about the creature] - it's black, its tail is as long as its body, it's bigger than a
