Thirteen people have now been arrested by Dyfed-Powys Police in connection with a protest at the South Hook LNG terminal.

They were arrested on suspicion of conspiracy to commit aggravated trespass by trying to gain access to the site from coastal paths and one person was also arrested on suspicion of conspiracy to commit criminal damage.

Five environmental protesters who had chained themselves together in a star formation in the entrance to the terminal earlier today were removed by police at 12.30pm this afternoon.

Police were alerted to suspicious activity at the South Hook site at around 4am this morning.

Chief superintendent, Paul Amphlett, commented: "Protesters have been removed from the site and those arrested are currently being questioned.

"We would like to thank the public and our partner agencies for their support throughout this operation. We are working with our partner agencies and are doing everything we can to minimise disruption and ensure the safety of the public and the protesters.

"The incident is still ongoing but we are working with the protesters and advising them of how they can continue with their protest within the limits of the law."

A statement from the protest group says: "These protesters, inspired by the 2006 camp for climate action, are targeting the construction of the LNG terminal and pipeline in South Wales. The action's aim is to disrupt the work to the largest extent possible."

Traffic was being diverted from the site in Milford Haven since dawn today because the protesters are preventing any vehicles from getting through.

Speaking outside the South Hook site this morning, spokesperson for South Hook LNG, John Constable, said: "Just before dawn this morning acting on advice, the police apprehended a number of people on the coastal path.

"There are now five protesters who are on the main road into the site. They are arranged in a star shape holding hands and their arms are in steel tubes.

"At 6am we started diverting traffic and all the guys coming to work on the site so there was a bit of traffic back up for a while."

"We recognise that in a democratic society, everyone has the right express their opinion in a peaceable manner on developments with which they disagree. We will work closely with the authorities to ensure that individuals are not put at any risk and that South Hook can continue to develop this important project in an expeditious manner."

Another South Hook Spokesperson has said the site is now back in "business as usual mode" and all vehicles that had been held up on the access road have now entered the site and traffic is flowing normally.
