Kate Middleton has reportedly been residing in her family home in Bucklebury for the past couple of weeks since the final bouts of her Hyperemesis Gravidarum. But the Duchess of Cambridge is already well enough to be out in the public again. October 21 marked her first public appearance since her second pregnancy was announced on September 8. However, her return to royal engagements reportedly also puts a risk to her safety. Armed guards were said to have been spotted outside at her parents' home in Bucklebury.

According to The Telegraph, fears of a terrorist attack called for the "royal protection squad" to be stationed outside Kate Middleton's family home in Bucklebury. A family of three happened to see this squad themselves on their way to Bucklebury Farm Park. The said farm is reportedly only a few minutes away from the Duchess of Cambridge's family home.

Mr. De Marco, 40, his wife Claire Lennon, 39 and their seven-year old daughter Mia, were reportedly headed to the farm last Thursday, October 23. However, a flat tyre on the BMW they were on prompted De Marco to stop at the roadside. According to The Telegraph, it didn't take long after stopping when armed men, with their guns drawn, surrounded the family.

"I was in a quandary, wondering what to do...then all of a sudden we found ourselves surrounded by policemen who were carrying guns," De Marco said.

"I didn't twig at first that they were connected with the Royal Family, but one of them mentioned Prince William and the Middletons' house nearby and we put two and two together," he added.

However, the protection squad was reportedly helpful once they realised the family was not a threat to Kate Middleton. They quickly put their guns away and even tried to help repair the tyre. De Marco recalled "they even drove off to visit a couple of garages in the area to see if anyone had a spare screw-nut so we could change the flat tyre."

The family didn't make it to Bucklebury Farm Park that day. But De Marco told The Telegraph they saw Kate Middleton, Prince George and her mother the following day at the farm's shop. Surprisingly, the royal protection squad was nowhere in sight when they drove off in their Range Rover.

The Metropolitan Police, which provides armed protection officers for members of the Royal Family, reportedly declined to comment on Kate Middleton's royal protection service. According to ParentDish, a spokesperson merely said "we do not discuss matters of operational security."
