LONDON — Scotland Yard is investigating after a package containing a mystery white powder was sent to American actress Meghan Markle and her fiancé, Prince Harry, according to a media report Thursday.

The London Evening Standard, which first reported the incident, said the powder purported to be the bacterial disease anthrax.

The letter was addressed to both Meghan and Harry and was sent to the couple’s home, Kensington Palace, in London. It sparked a security scare and never reached the pair, the Standard reported.

Scotland Yard didn't immediately respond to a request from USA TODAY for comment. Kensington Palace declined to issue any statement.

The couple are due to wed at Windsor Castle, just outside London, on May 19.
