Someone sent princess-to-be Meghan Markle a letter purporting to contain anthrax, according to a report.
Police at Scotland Yard are investigating after a message with white powder arrived at Kensington Palace for Markle and her fiance Prince Harry on Feb. 12, the London Evening Standard reported Thursday.
The letter said it contained the deadly agent anthrax, but both it and a letter sent to the British government the next day were found to be harmless, the report said.
Packages sent to the royals are already subject to security screenings, and the letter is not believed to have reached Markle.
The former actress, who is originally from Los Angeles and starred in the TV series "Suits," is set to marry the prince in May outside the British capital at St. George's Chapel.
Her glamor, foreign nationality and biracial identity brought praise from many observers who say she could inject new life into a royal family often seen as stodgy.
However, some British press have been criticized for racism in their coverage of the future princess, with the Daily Mail blasted over a headline that said she was “(almost) straight outta Compton.”
