In reply to Bazza S:
I was at the top and chatting to the coastguard. They told me that the person had an injured leg and arm but was fine, they went to Bangor hospital.
I don't know the people involved though, so hopefully they are okay and recovering well. I'm sure being in an incident like that is stressful for all and would explain (to some extent) irrational behaviour.
We were totally unaware of anything going on till the helicopter turned up along with a load of coastguard guys.
