Masked burglars have stolen farm vehicles from the Windsor Castle estate, it has been reported.
Two men scaled a 6ft fence at night and used a stolen truck to break through a security gate at the royal venue, according to The Sun newspaper.
The Prince and Princess of Wales and their children were sleeping in their home nearby, the paper adds.
The men reportedly fled with a pick-up and a quad bike that were stored in a barn.
The burglary is said to have happened on October 13.
The King was not in residence but the Prince and Princess of Wales were believed to be at Adelaide Cottage with George, 11, Charlotte, nine, and six-year-old Louis.
It is five minutes away and the family are regularly seen using the wrecked gate — the nearest exit to their home.
In a statement to the newspaper, Thames Valley Police said: “At around 11.45pm on Sunday October 13, we received a report of burglary at a property on Crown Estate land near to the A308 in Windsor.
“Offenders entered a farm building and made off with a black Isuzu pick-up and a red quad bike. They then made off towards the Old Windsor/Datchet area.
“No arrests have been made at this stage and an investigation is ongoing.”
