As British Prime Minister David Cameron prepared for the announcement of a controversial new fracking law in the UK, Greenpeace activists gave the leader a taste of his own policy early Wednesday when they set up a mock fracking operation at his country estate.

“David Cameron wants to rob people of their right to stop fracking firms drilling under their homes – surely he won’t mind if we kick off the under-house fracking revolution below his own garden.” —Greenpeace

Police were called after the activists, wearing hard hats and day-glo vests, erected security fencing around Cameron’s cottage in the Cotswold hamlet of Dean, Oxfordshire. Signs were posted that read: “We apologise for any inconvenience we may cause while we frack under your home,” and ordered complaints to be directed to the PM’s office.

“David Cameron wants to rob people of their right to stop fracking firms drilling under their homes – surely he won’t mind if we kick off the under-house fracking revolution below his own garden,” wrote Greenpeace UK energy campaigner Simon Clydesdale in a statement.

After police ordered the removal of the “fracking site,” Greenpeace issued this tweet marking the irony of the events.

The group also released this video of the action:
