Four people have been arrested at one of the UK's new gas-fired power stations, bringing to an end a week-long protest at the site.
Nottinghamshire Police said the final two women climbed down from a tower at West Burton power station in Nottinghamshire on Monday morning and were arrested on suspicion of aggravated trespass.
A man and a woman were also arrested on Sunday afternoon, a force spokesman said.
Twenty-one people have now been arrested on suspicion of aggravated trespass since the protest began.
A force spokesman said the protesters came from across the country with none living in Nottinghamshire.
The "No Dash For Gas" campaigners have been protesting at the site since making their way into the plant in the early hours of last Monday.
More than 20 are believed to have entered the site, with 16 climbing up and securing themselves to two chimneys at the plant.
The campaigners said they were protesting against moves to build new gas-fired power stations such as West Burton, warning they would leave the UK dependent on a polluting and increasingly expensive fossil fuel for decades.
The Government has backed the development of up to 20 gas-fired power stations as part of its strategy for future energy supplies.
Ministers insist that continuing use of gas without technology to trap and permanently store carbon emissions is compatible with targets to cut greenhouse gases to tackle climate change.
