British royals Prince William and Prince Harry were left shaken following a bomb scare at the British Army's Sandhurst Military Academy on Saturday (14JAN06).

The alert was sounded when a suspicious box was discovered just 100 metres (328 feet) away from the princes' living quarters - but a closer inspection revealed the container was merely a lunchbox full of clay.

A royal source says, "There was a massive security flap and it was a big relief when it was all over."

After 90 minutes it emerged the box was a fake bomb specially made for training purposes - which had fallen from the back of a vehicle earlier that day (14JAN06).
