I know that area well as I fossil hunt around those bays alot, the cliffs are very unstable and I would never go climbing on them for fossils, hence why they are good fossil collection grounds, constant fresh falls producing fossils.
Jet is worth a good bit of money in the right size pieces or quality.
As said previously "general term for a climber is poles apart", shame this has happened.
"A friend who was at the scene was unhurt and a spokesperson for Whitby coastguard, who attended the incident and cared for the second man, said: “He just said his friend was going down the cliff and they had tied this rope round a rock. But it moved and down he went.”
Sounds like some random blokes hunting for fossils or jet with some basic abseiling kit didn't understand what constitutes a sound anchor and unfortunately one of them paid the price.
Still not sure why the other guy was arrested though, He surly can't be legally responsible for the quality of the other guys anchors he decided to ab off.
