Meanwhile, a 50-year-old diver has died at a 300ft deep quarry 'pool of death' in Snowdonia - the scene of numerous previous tragedies.
He was at the Dorothea Quarry in the Nantlle Valley, a popular spot for amateur divers, yesterday.

An air ambulance helicopter and RAF rescue helicopter from Valley, Anglesey, flew to the scene after emergency services were informed that he was in cardiac arrest but the man died despite efforts to save him.

Police said that the coroner had been informed. Mining stopped at the site in the early 1970s. More than 20 divers have died there.

Sad, but so much depends on the details that so far haven't been told.

Incidentally, at its deepest it's 109 metres, of icy cold fresh semi-opaque water. That's 358 feet. There are many large and complex shelves and overhangs to catch the unwary, and most of the many fatalities that have occurred there have been because the diver couldn't find the way to the surface. It's inherently a very dangerous place to dive, and there have been numerous attempts to close it off to divers. There are no facilities there or anywhere in the area, but that doesn't put people off. Fences can be cut or climbed, gas tanks can be carried in a car a hundred miles or more. But the nearest chamber is hours away. Not a dive for the faint of heart or ill-prepared.
