The trio climbed on to lorries outside energy firm Cuadrilla's fracking site in Preston New Road, Little Plumpton, in a protest last July which lasted almost 100 hours.

The three had been held in Preston prison, which was the scene of several protests over what were described as 'excessive' sentences.
