Police have arrested a man on suspicion of a public order offence and possession of an offensive weapon near the home of Andrew Mountbatten-Windsor.
Norfolk Constabulary said in a statement that officers were called to Wolferton shortly after 7.30pm on Wednesday "following a report a man was behaving in an intimidating manner in the village".
The force said: "Officers attended, and the man was arrested on suspicion of a public order offence and possession of an offensive weapon.
"He was taken to King's Lynn Police Investigation Centre for questioning and remains in custody."
According to the Telegraph, the arrest came after the former prince was confronted by a balaclava-clad man while walking his dogs.
The man was said to have spotted Andrew 50 yards away, then exited his vehicle and made his way towards him while shouting.
The outlet reported that the incident took place on public land in a lane close to the Sandringham Royal Parkland.
Andrew moved into Marsh Farm in Norfolk last month, after moving out of Royal Lodge in February.
The palace had announced last October that the King had started the process of removing the style, title and honours of the former prince after the Jeffrey Epstein-linked allegations against him had started to "distract" from the Royal Family's work.
