“Other people were saying around us a worker had fallen backwards onto the beach below.
“The ground ambulance arrived and an orange tent was popped up.
“The air ambulance flew away and the police still have the scene cordoned off and we saw a couple of official looking guys in suits at the scene.
“We have just come down for a day and we just happened to see it unfolding – it is very sad after what all that has happened to the pier in recent weeks.”
