A TRESPASSER sparked a security scare by snooping around the King’s private garden at Windsor Castle while His Majesty was there.

The man, 39, was arrested in the grounds of the royal residence on Tuesday night.

Police said he was taken into custody under the Mental Health Act.

A source said the trespasser was found in the gardens of the Berkshire tourist attraction.

They added: “There was a security breach at Windsor Castle.

“A man was found wandering around the King’s private garden. He was arrested.

“The whole thing happened while the King was in residence.”

Another source confirmed to The Sun: “It’s understood the King was in residence at the time of the break-in, but was not in any danger.

“The intruder was not believed to be holding a weapon, and was alone.

“A sweep of the Castle grounds confirmed no-one else was involved.”

A man who broke into Windsor Castle with a loaded crossbow to kill Queen Elizabeth in 2021 was sentenced to nine years in jail, with a further five years on extended licence.

Jaswant Singh Chail, 21, climbed into the castle grounds with the weapon on Christmas Day and later declared: “I’m here to kill the Queen.”
