A 22-year-old man scaled the fence of Buckingham Palace in the early hours of the morning and got just metres away from the Queen. The intruder was banging on doors in an attempt to get inside the palace as the head of state slept in her bedroom. Police on site took around four minutes to detain him as they tried to assess if he was armed, sources say. Doors to the 93-year-old monarch’s home are locked up in the early hours of the morning, so the trespasser was unable to get inside. The royal standard flag was flying at the palace, which could have given the invader a clue that the Queen was at home.
