People reports that Prince Harry and Meghan Markle were also the victims of an anthrax scare earlier this month.
Just like Donald Trump Jr. and his family, the prince and his bride-to-be received an envelope containing white powder. It was sent to the couple at their Kensington Palace home.
“Police are investigating after a package containing a substance was delivered to St. James’s Palace on Monday, February 12,” a spokesperson at the Metropolitan Police tells PEOPLE, confirming that no arrests have been made.
The couple was spared part of the ordeal that the Trumps underwent. The envelope—reportedly addressed to both Harry and Meghan—was intercepted and sent to St. James’s Palace for sorting.
The police spokesman said that “the substance was tested and confirmed as non-suspicious." However, “Officers are also investigating an allegation of malicious communications which relates to the same package.”
According to the Evening Standard, which first reported the story, the envelope also contained a racist message.
The scare will likely put Scotland Yard on high alert for the couple’s wedding at St. George’s Chapel in Windsor on May 19. As part of the wedding celebration, the newlyweds will take part in a carriage procession around the streets of Windsor.
This isn't the first scare for the royal family. Last September, a woman was arrested for breaking into Prince George’s school, and in October, a terror suspect allegedly encouraged ISIS extremists to attack Prince William and Kate Middleton‘s son at school via a chilling web message.
Kensington Palace declined to comment.
