A security breach, reportedly the worst in thirty years, clearly has police on edge at Buckingham Palace, reports CNN's Erin McLaughlin.
Two men were arrested for allegedly targeting the Queen's main residence, which is packed with priceless works of art and jewelry.
Official say a man scaled a 12 ft. fence and broke through a door while his accomplice waited outside the palace.
On display is a temporary exhibition which is open to the public to celebrate the 60th anniversary of the Queen's coronation that includes a spectacular diamond crown that the Queen can be seen wearing on British stamps and coins.
Though nothing was stolen, no one was hurt in the incident and the Queen is still on vacation at her castle in Scotland, the incident caused local authorities to be on high alert.
Just two days later, London's metro police confronted a would be intruder wandering around the palace gardens, shouted and demanded he identify himself.
The problem was the intruder was actually the Queen's son, Prince Andrew, simply enjoying a walk.
Scotland Yard later apologized to the Prince who took it in stride saying in a statement:
"The police have a difficult job to do balancing security for the Royal Family and deterring intruders. Sometimes they get it wrong."
