The Top Gear presenter has been in a legal battle with walkers on the Isle of Man for six years, after he diverted a footpath that he thought ran too close to his vacation house. The walkers say Clarkson obstructed a footpath he had no right to obstruct, since it's a public right-of-way. So far, the government has sided with the walkers.
The walkers started a group a few years ago called PROWL, Public Rights of Way Langness, to better fight the battle, but PROWL denies any knowledge and involvement in the vandalism.
