About 30 eco-protesters have broken into an EDF Energy site with the intention of setting up camp. Some have already climbed the only operational chimney at the Midlands-based gas power station. An EDF representative said the operational chimney was “immediately shut down to protect protesters who had placed themselves in potential harm”. A police spokesman added: “Negotiations have begun to encourage the protesters to end their demonstration.” Five women have already been arrested on suspicion of aggravated trespass.
