A man claims to have have multiple experiences with extra-terrestrials over the past 50 years.
Russ Kellett, from Bradford, says he was just four years old when he had his first encounter with UFOs.
Recalling the meeting, the 58-year-old says he saw a man standing in his back garden wearing what appeared to be a 'space suit and a helmet'.
He said: "He was walking in my garden - I could not believe it. I waved and he put his hand up. There was a silver object which I thought was a dustbin.
"He walked behind this silver object and the next thing it juddered and went up. I thought, 'What the heck is this'."
And over the years, he has had countless more otherworldly experiences.
When he was just 12 years old, Russ, who is now a businessman and UFO hunter, says he 'lost' a number of hours while playing alone near some woods.
He says he saw a 'light in the sky' before everything went dark and a strong wind began crashing against the trees.
Russ says the experience was "really bizarre and a little bit frightening" but he thinks it was some kind of 'craft' in the sky.
And then, a few years later, he says he was abducted while out riding his motorbike.
Detailing what happened, Russ says he was injected in the back of the neck.
He has since written a book about his experiences, called Russell Kellet is E.T. Rider.
The synopsis for the book reads: "A man's account of countless close encounters with alien craft and abductions by an alien race.
"Taken by a group of aliens and put into a military unit, trained to fight as a super-soldier against their enemies on this planet and on many others in our universe.
"Coming to terms with memories of an alien planet and fighting different alien races as well as human races on Earth."
A year ago, one of his most outlandish tales caused a media stir because it involved former Take That singer Robbie Williams.
Russ says he saw Robbie boarding a spaceship in 1999 and that he was part of his 'military unit'.
According to reports, the singer refused to comment on the claims but didn't deny that it had happened.
Discussing the bizarre tales, Russ said: "A journalist said that what I told him is like an A-movie."
Russ reportedly likes to hunt for extra-terrestrial life in North Wales, and says that Dee Estuary is a particular hotbed of activity.
And last year, he invited celebs interested in seeking out UFOs to get in touch with him.
He told the Leader: "To them and any other celebrties who are getting in to this, if they want to get involved they can get in touch with me.
"I want them to know its genuine, we're not after money, we want to go out for a couple of nights and hopefully make contact."
