Witness Lissy Jackson said: ” I saw a number of rescue workers at the scene, all crowded round the rocks attempting to free the man.
“He had an injured/trapped leg so they did not have much success. I later then saw 2 large trucks pull in, with equipment to aid in breaking to rocks to break the man free.”
Harry Weaver, a Sheringham resident who lives close to the promenade, said he had seen a specialist Hazardous Area Response Team (HART) ambulance heading towards the scene shortly after 8pm.
He added: “The incident itself is blocked from view, I just saw the coastguard fly down at first followed by fire, ambulance and later more specialist fire appliances.”
The man is now being cared for by the East of England Ambulance Service, and no details have been given of his age, or where he is from.
Retired Coastguard station manager Stuart Facey told the North Norfolk News he was walking his dog when the Coastguard arrived.
“I saw someone obviously stuck in the rocks, it was high tide and water was coming over him so it was a very scary situation,” he said.
“I’ve seen people climb into the cavities in the rocks and the problem is that even if you are able to move a rock to free someone who is stuck, another can fall into its place, it can be a life or death situation.”
