Over 1,000 climate change protesters gathered at Ratcliffe on Soar power station in Nottinghamshire last Saturday to protest against the continuing use of coal power stations.
The protesters were met by police violence, horses and dogs. One protester is believed to have suffered a heart attack.
On Saturday evening police dogs were let loose in the forests around the power station leading to a number of injuries to activists.
The power station is owned by E.on and is one of the biggest carbon dioxide polluters in Britain. E.on also owns the Kingsnorth power station in Kent, the expansion of which was recently put on hold.
This protest was one of a number organised in the lead up to the climate talks in Copenhagen in December.
