Last month, robbers broke into a farm on the Windsor Castle estate and took a quad bike and a pickup truck, according to Thames Valley Police.
On October 13, just before midnight, the burglars scaled a six-foot fence to gain entry to Shaw Farm.
The intruders stole a red quad bike and a black Isuzu pickup after breaking into a farm building.
While fleeing, they set off an alarm, causing damage to a security barrier at the farm gate that the royal family frequently uses.
According to reports, Prince William, Catherine, Princess of Wales, and their three kids were in Adelaide Cottage when the break-in occurred.
But there was no sign of King Charles or Queen Camilla.
