EMERGENCY services, business and tourism leaders are all calling for people to heed the warnings to stay away from cliffs.

The plea comes as Broadchurch is about to air and west Dorset photographer Graham Hunt captured this image of a father taking pictures of his family on what is clearly a huge rock fall.

Business and tourism leaders know that the hit ITV drama is a great draw for tourists - but they don't want to see a repeat tragedy like the death of Charlotte Blackman, who was killed by a 400-ton rockfall in July 2014.

Emergency services are the people who have to respond when something goes wrong and they can pay a heavy price too, they say.

Simon Miles, from Lyme Bay Rib Charter, chairman-elect of the Bridport and District Tourism Association said: "Heaven forbid should there be an accident of any level.

"It does impact on everybody in the area, whether you are reliant on tourism as an income or whether you are just a resident. It will impact on you in some way.

"Great care does have to be taken. I know there is a lot of resistance to signs because they are seen as unsightly and who reads them anyway but I think it is important that they are there correctly worded and in a suitable location that people can't miss.

Photographer Graham Hunt said he has seen people risking their lives for years and this family were actually climbing on a rock fall from last August - one that saw emergency services spend more than eight hours checking no one was trapped.

He said: "Over the years you keep coming across it and you think 'oh no not again'.

"School holidays seem to be the worst time.

"Over the years you find that if you say anything to people they tell you to mind your own business.

"They resent it and think they know best.

"A couple of the children were climbing on the rocks anyway and the father had his camera in his hand and started beckoning the others over to the top of the pile of rocks and even got the dog over to go up there."

West Bay coastguard station officer Mark Collins said: "How many more messages can we put out there? We can't put any more out, there are signs, your paper has run articles.

"It is either people not understanding the message or not understanding the risks for real.

"They are almost taking our warnings that we want to stop their fun, which is obviously not what we are there for.

"When something happens it is the emergency services and members of the public that see it happening and it sticks in people's minds. It is not just the people who get hurt - it is those that witness it and us and the fire brigade and it involves an awful lot of manpower and costs.

"The last one last year when they thought there was someone under it I hate to think what that cost. It was an incredible amount of manpower and equipment and that obviously takes it away from being available for other things as well.

"There was a rockfall and someone was seen darting out of the dust and we were there for eight and a half hours until we were absolutely sure there was no one under there

"The message is there are real dangers."

He said the retained fire fighters and coastguards were not used to seeing gruesome sights - like Charlotte Blackman - in the way ambulance crews were.

He added: "You are suddenly faced with, without being gruesome, body parts

"Various people deal with it in various ways and some people did need counselling. That is a side effect of an incident and it is preventable if people keep away.

"An accident is an accident and no one knew that that cliff was going to fall at that second but the warnings are there.

"The geologists have said they are unstable. This is not a new phenomenon - they ave been unstable for millennia.

"There have been several small falls along West Bay. It doesn't have to be a several hundred ton fall that will injure or kill someone - it can be a single rock

"Broadchurch is such a draw to the area and we need to reiterate the message."
