Prince William and Kate Middleton were deeply shocked after burglary near their Windsor Castle home, a new report has revealed.

According to Closer Magazine, the Prince and Princess of Wales have been left shaken after masked raiders climbed a six-foot fence and stole vehicles from Shaw Farm, located in the grounds of their family home, Adelaide Cottage.

The incident occurred just five minutes away from where the royal couple and their three children, Prince George, Princess Charlotte, and Prince Louis, were asleep.

An insider told the publication, “William and Kate have been pretty shaken up, and it really reinforces the importance of being vigilant and protecting their family’s security at all times.”

“It’s a huge concern that these raiders were able to scale the fence and make off with stolen vehicles, and the fact it happened when the Waleses were so close by and fast asleep was a big shock to process when they found out,” they added.

"Like any parents, they’re constantly worrying about the welfare of their children. It’s by far their number one priority, so naturally, it’s frightening and extremely alarming that this happened in such close proximity.”
