An 83-year-old man is facing arrest after putting a sign up on his property calling it Ugly Fence House.
Roy Bentley and wife, Rita, from South Wooton near King's Lynn put the sign up in protest over a fence put up by his neighbour.
Mr Bentley says the fence is "ugly" and the fence posts are facing his property. He is refusing to take the sign down.
A spokesman for Norfolk Police said: "Those involved in the fence dispute have been spoken to by officers and one resident has been issued with a notice outlining why the alleged behaviour is unacceptable and may constitute an offence under the harassment act.
"There is also the possibility that continued actions may result in arrest or prosecution."
