British royals Prince Charles and his wife CAMILLA, DUCHESS OF CORNWALL are at the centre of a security alert after an intruder carrying a pitchfork was arrested within yards of their mansion on their rural England estate. The couple were asleep when the 55-year-old suspect, who police believe to be an animal poacher with a criminal record, was detained after entering the grounds of Highgrove in Gloucestershire at 4am yesterday (30JAN07) morning. The intruder, who was carrying a pitchfork and a sack, was detained by security after triggering underground sensors when he jumped over a fence. As WENN went to press a royal spokesperson had yet to comment on the incident.
