Five climate change protesters have been arrested on suspicion of aggravated trespass at the site of a gas-fired power station.
Nottinghamshire Police said some of those involved in the protest had scaled buildings at West Burton Power Station after gaining access to the site at about 1.20am.
A police spokesman said: "Around 10 (protesters) are thought to have climbed the water towers and have secured themselves to restrict their removal.
"Searches are ongoing to find a number of other people who are also believed to have gained access to the site."
