A POTHOLER has told of the terrifying moment he stuck in one of the UK’s most treacherous caves as water flooded in.

Video footage of Saltburn man, Bob Johnson’s ordeal has become a YouTube hit with more than 200,000 hits.

WARNING: This video contains strong language.

But the 39-year-old Redcar steelworker said he couldn’t watch it himself.

Mr Johnson became wedged in freezing water in Lost John’s cave on Leck Fell, Lancashire earlier this year. He had been filming with a head-cam on his helmet, but passed the camera to his friend as he struggled to free himself as water rushes in.

Friends can be heard urging him to relax until, after five minutes, other cavers pull him free. He was bruised but unhurt.

“I have been caving since, but I won’t be trying that again,” he said. “When I got out I went straight for a beer.”

As for the footage, Mr Johnson said, “I can’t watch it, I was like a cork in a bottle.”
