An armed man has been arrested after trying to storm Windsor Castle where the Queen was celebrating Christmas with her family.
Police said the intruder was carrying an offensive weapon but did not break into any building on Christmas morning.
Thames Valley Police said the suspect is in custody and the royal family has been informed.
They added that a 19-year-old man from Southampton has been arrested on suspicion of breaching or trespassing on a protected site and possession of an offensive weapon.
Officers from the Thames Valley and the Metropolitan Police responded to a security breach at approximately 8:30 am inside the castle grounds in Berkshire.
Sobt Rebecca Mears said: “An investigation is underway following this incident and we are working with colleagues from the Metropolitan Police.
“The man was arrested on suspicion of breaching or trespassing on a protected site and possession of an offensive weapon. He remains under arrest at this time.
“We can confirm that the security operations began within moments of the man entering the ground and not entering any buildings,” he added.
Members of the royal family have been informed of the incident. We don’t think there is a greater danger to the public.”
The Queen was celebrating Christmas in Windsor with Prince Charles and his wife Camilla, the first year since the death of her husband, the Duke of Edinburgh.
Charles, Camilla, Edward, and Sophie, with their children Louise and James, attended a chapel service at St George’s Chapel, in the castle grounds, at 10.45 a.m. on Christmas Day.
