A pitchfork-wielding intruder has broken into the grounds of Prince Charles's home in Gloucestershire while he and Camilla were asleep inside.
"He was detained within the grounds and did not get into any of the buildings," said Inspector Tony Rymer, of Gloucestershire Police.
A 55-year-old man from Bristol was arrested on suspicion of trespass on the Highgrove Estate early on Monday.
The man was questioned at Stroud police station and bailed until 26 March.
A Clarence House spokesman said: "This is a police matter and it is for the police to make a comment."
