According to an article from the Daily Mail UK,
“A suspected burglar has been arrested after being discovered in a royal state room at Buckingham Palace.
Police said the man was found ‘in an area currently open to the public during the day’ after scaling a 12ft fence to get into the palace.
A security review has now been launched following the break-in. No members of the royal family were present at the palace at the time of the incident.
The man has been arrested for burglary, trespass and criminal damage.
A second man was arrested outside the palace for conspiracy to commit burglary following the incident shortly before 10.30pm on Monday.
According to reports, police and security rushed to the palace after motion senors were set off.
A spokesman for the Metropolitan Police said: ‘Both men have been bailed to return to a central London police station and enquiries continue.
‘A review of the specific circumstances of this incident is being carried out. No members of the Royal Family were at Buckingham Palace at the time of the incident.’
A spokesman added that security would form part of the review.
According to The Sun, a source close to the investigation said: ‘This breach of security is being treated with the utmost seriousness.’
Buckingham Palace have not commented on the incident.
The Queen has been spending her summer break at Balmoral Castle since the beginning of August and is not expected to return to the palace until October.
She is expected to make her traditional appearance at a Highland Games today.
The Braemar Gathering is held each year just a short distance from the Balmoral estate in Aberdeenshire.
The break-in is one of the most serious security breaches at the palace since 1982, when Michael Fagan evaded guards to get inside the Queen’s private chambers while she was still in bed.
The unemployed father of four, 31, spent around 10 minutes talking to the Queen after he climbed over the palace walls and up a drainpipe.
The Queen managed to raise the alarm when Fagan asked for a cigarette, allowing her to call for a footman who held him until police arrived.”
