Jackie Brookes is said to have been at the site in North Yorkshire serving tea and home made cake to protesters and police for the last month.According to North Yorkshire Police, she and other people were moved this morning because of fears that a nearby tower made of wooden pallets might collapse and injure them.County council officials will assess the safety of the tower later today. Superintendent Lindsey Robson, of North Yorkshire Police, said: “We have a duty to ensure the safety of everyone involved in protests at Kirby Misperton.“Officers had to move several people away from a tower of pallets this morning, after we received advice from the local authority that it may not be safe."While some people were unhappy, we spoke to them and asked them to move for their own safety, which they did.“We will always act to protect people from harm.”But the move attracted anger from some protesters at the site, where Third Energy is to conduct a series of underground test fracks to produce gas for its nearby power station.One wrote on Facebook: "I popped up to Kirkby Misperton this morning to stand in solidarity for a couple of hours with all the lovely people up there."I was having a chat and just about to get a cuppa from the wonderful Jackie (who is in her 80s and has been serving tea and home made cake to the protesters and police alike for the last month, as featured, amazingly, in the Daily Mail)."All of a sudden a lot or police approached us demanding me and Jackie (and her table) immediately move further away from the 'dangerous structure' (that was too far away to hit us, even if it had spontaneously fallen over in our direction!)."I was ordered (farcically) to 'step away from the picnic table' (yes, really). When the indomitable Jackie refused to do exactly as she was told, the second she was ordered to; this is what happened next."More than 20 people have been arrested at anti-fracking protests in Kirby Misperton, where Third Energy was granted permission to frack in 2016.These include women who locked themselves to a concrete-filled tube, and another person who protested on top of a lorry.Separately, police said this afternoon that they "facilitated a 20-minute peaceful protest outside the hydraulic fracturing site".This involved a group of about 20 protestors sat and stood in the road in front of the entrance to the site, as four heavy goods vehicle waited to leave.Fracking is designed to recover gas and oil from shale rock using high-pressure water mixture and the upcoming tests will see the company attempt the process at five different depths to see whether it is commercially viable. While there are no other current applications, the company has six existing well sites in Kirby Misperton, Malton and Pickering where it has said it may consider "further appraisal activity".For its supporters, including the Government, fracking represents a huge opportunity to reduce the UK’s reliance on overseas imports, which has grown in recent years as a result of the decline in North Sea oil and gas production. But detractors, including dozens of activists who have been besieging the site for the past few weeks, highlight environmental and safety concerns.
