A busy main road in Balcombe had to be closed today as a van, protesting against fracking outside Cuadrilla, blocked the road.
The van was parked diagonally across the B2036 London Road at 11am today, blocking both carriageways.
A woman then locked herself to the top of the van.
Superintendent Lawrence Hobbs said, "This is once again causing significant disruption to the local community at a time when there are increased vehicle movements as the site is being prepared for closure."
Exploratory oil drillers are beginning to pull out of the site at Balcombe.
Police have warned that there is likely to be on-going disruption this week as up to 20 vehicle movements a day, necessary to clear the site, have to be escorted in and out by the police to reduce the risk of them being delayed even further by protesters.
