A British man who vanished for nine days walked 100 miles barefoot - and has no memory of his bizarre trek.

Mark Stott, 42, suffers from a rare disorder that makes him forget who he is and he loses days of memory at a time.

He vanished during a routine hospital check-up near his home in Bristol and was found more than a week later in a supermarket car park in Swansea.

He has no memory of the missing days but believes he must have crossed the Severn Bridge and walked because his feet were blistered and bleeding and he had lost more than 14 pounds.

"I haven't got the foggiest what happened or how I got to Swansea. My legs ache and my feet are really blistered, Stott said. "Now I'm trying to get my head round the fact that I thought I had only been missing for two days but I was actually missing for a week and two days."

Mark's last memory before he disappeared on May 21 was eating breakfast at Frenchay Hospital, where he was staying under observation.

Police launched a massive search but could not find him. Then on Sunday morning a shopper in the Sainsbury's car park spotted Mark in a dazed state.

The former driving instructor was taken to hospital, where doctors found that apart from dehydration he was in good condition.

He was diagnosed with Non Epileptic Attack Disorder—a form of seizure—after several disappearances earlier this year.

"It's all been so surreal. When I got the call from the police I didn't know whether to laugh or cry, said Debbie Glasse, 37, Stott’s fiancée and mother to their 20-month-old twins Abigail and Amber.

"We've been living minute by minute not knowing if Mark was dead or alive. He didn't even recognize me when I first saw him but the more I spoke to him things started to come back," she said.
