The owner of the farm where anti-fracking protesters have set up camp in West Sussex has said the activists came on his land "without permission".
Richard Ponsford, who owns Sidney Farm in Balcombe, said: "About three or four vans came on to the field and they spent about three hours barricading the field in.
"I certainly did not give my permission. There is no way I would have allowed them in at all."
He was not reassured by the activists' promises to leave the field in the same state as they arrived, saying: "They might not know how much damage they might do."
Green MP Caroline Lucas was among those arrested at a sit-in aimed at halting plans to drill for shale gas in a West Sussex village.
As campaigners in Balcombe begin a five-day camp in protest at fracking, supporter Tisha Brown tells ITV News why it's such a crucial issue.
The chief executive of Cuadrilla Resources, Francis Egan, told ITV News the company "will complete our approved work" at its Balcombe site.
