A 22-year-old man has jumped the fence into Buckingham Palace, the royal Palace in England.
The intruder, whose identity has not been revealed, got as close as just metres away from the Queen during the incident on Wednesday.
According to Metro.uk, he was banging on doors, in an attempt to get inside the palace while the queen, 93, was resting.
It took police about four minutes to detain him, as they tried to assess if he has weapon, the report also said, adding that doors to the monarch’s home are locked in the early hours of the morning, which prevent him from gaining entrance to the queen’s room.
The royal standard flag was flying at the palace, which could have given the invader a clue that the Queen was at home.
A royal insider told The Sun: “This intruder got into the Palace almost 37 years to the day since Michael Fagan ended up getting inside the Queen’s bedroom.
“There is a genuine theory and very real fear that he could have been launching a copycat operation. How is it possible all these years later that someone can climb the fence and get right inside the grounds without being stopped immediately?
“What about heat censors and CCTV? The Queen’s safety should be paramount.”
It is understood that the queen was the only senior member of the royal family sleeping at the palace because of ongoing refurbishment work.
Scotland Yard say the man was arrested on suspicion of trespass and was held at about at 2.00pm by officers from the Met’s Royalty and Specialist Protection Command.
It added that no weapon was found on the man and that the matter is not being treated terrorism-related.
It is not the first time Buckingham Palace’s security has been breached. On July 9, 1982, an unemployed man, Fagan, jumped the palace walls and got into the Queen’s bedroom.
The monarch was said to have pushed the panic button by her bed, but got no response while the 31-year-old schizophrenic began talking about his family problems.
She phoned the switchboard, but the operator thought it was a prank and couldn’t have been the Queen herself.
Fagan broke a glass tray and threatened to cut his wrists with it as he sat on the queen’s bed.
The monarch’s long-time aide, Paul Whybrew, eventually arrived and began talking to Fagan to calm him down.
Whybrew wrestled with him and pushed him outside where a maid who saw them called the attention of a policeman.
