Green Party Member of Parliament Caroline Lucas was among 25 people arrested Monday for staging an anti-fracking protest in Balcombe, a town in southern England.
Police made the arrests while clearing a group of about 200 demonstrators who had blocked the entrance to the drilling site operated by energy company Cuadrilla Resources.
Two other protests were staged Monday in Britain against hydraulic fracturing, or fracking, a controversial method that involves pumping a pressurized fluid - usually composed of water, sand and chemicals - into a shale formation to create a fracture in the rock layer and release trapped petroleum or natural gas.
About 20 protesters blocked the entrance to Cuadrilla's headquarters in Lichfield, a city in central England, while half a dozen people superglued themselves to the doors of the London offices of public relations company Bell Pottinger, which works for Cuadrilla.
"I'm proud of the people around me who have put their bodies where the police are. They have tried to use the democratic processes, tried to raise the issue through those democratic panels," Lucas said.
The MP said officials were ignoring the threat posed by climate change.
"The government isn't listening. Climate change is the greatest threat that we face and I think that people are right to try and take action against fracking," Lucas said.
Anti-fracking groups contend that the technique pollutes aquifers and causes earthquakes in the areas where drilling takes place.
Cuadrilla Resources condemned the protests at its headquarters and drilling site.
"Protesters broke into our Lichfield office, harassed our staff and chained themselves to filing cabinets," Cuadrilla said in a statement. "We condemn all illegal direct actions against our people and operations."
Prime Minister David Cameron called on the public last week to support fracking, saying it would create thousands of jobs and cut energy costs in Britain. EFE
