Update from the Orange Group: 1 arrest for criminal damage and resisting arrest, some kind of fracas / scrum in centre of crowd. Unclear what actually happened. Police tussling, some people whacked. Police dragged one person out of the crowd. Crowd shouting "shame on you, shame on you". The group has now got to A228, coming up to roundabout with the road ahead to power plant. Static at the moment due to police.
