POLICE are working with the Port of Milford Haven, to curb the dangerous increase in people 'tombstoning' into the Haven.

During the recent hot weather, crowds of up to 100 people have been gathering on the water's edge to watch people jumping in.

But the dangers surrounding these jumps from height into the busy shipping area have prompted authorities to take legal action.

"As well as the obvious dangers such as cold water shock, currents and drowning, there can be many hidden sharp objects underneath the surface," said a Port spokesman.

"Cases have also been reported where individuals have jumped in front of and on top of moving vessels, causing distress to the owners.

"When challenged by port staff and neighbourhood police officers, many have displayed threatening behaviour."

Chief Executive at the Port, Alec Don, said “Unfortunately the situation has reached a stage where we are having to take legal action to prevent people from risking their lives around the marina and docks.

"We are seriously concerned about the safety of these people.

"We will not tolerate this activity on our property and neither will we tolerate threatening behaviour or abusive language, in person or online, directed towards our staff - who are only acting to keep people safe.

"Tombstoning has killed 20 people in the last eight years, so the risks are very real.”

Added police sergeant Terri Harrison: “Police are aware of this issue and will work with the Port of Milford Haven to educate young people about the dangers and try to get the message over of the possible tragic consequences of this practice.

“Officers will be patrolling the area and will provide advice and warning to people they see putting their safety at risk.

"Action will be taken if any offences are identified.

"School Community Police Officers have also given an input at the local school.

"We want people to enjoy our beautiful coastline, but in a safe and responsible manner.”

The Port will be running a safety awareness event for young people in July.
