'Fracking' firm scaling back operation at Balcombe

Energy firm Cuadrilla has said it is scaling back work at an exploration site in West Sussex on police advice.

The company has been drilling for oil near the village of Balcombe but has not ruled out using the controversial technique of fracking to release gas.

Police believe environmental activists at the site are about to begin a campaign of civil disobedience.
