It’s been confirmed the man was “quickly challenged by Met police officers and arrested” after he gained access to the grounds of the castle.
Thames Valley Police said
the man did not enter the inner grounds of Windsor Castle.
He has been bailed and an investigation is ongoing by Thames Valley Police.
The Duke and Duchess of Cambridge live in Adelaide Cottage, which is located on the Windsor estate. However, no members of the royal family were in the castle at the time of the incident, according to Sky News.
There was another security scare at Windsor Castle in October when two masked raiders broke into farm buildings on the estate.
In a statement given to People, Thames Valley Police said at the time: “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.”
