A Metropolitan Police spokesperson told PEOPLE at the time,'Police are investigating after a package containing a substance was delivered to St. James’s Palace on Monday, February 12.'
The package, which was addressed to both Harry and Meghan, was intercepted and sent to St. James's Palace for sorting and the 'substance was tested and confined as non-suspicious,' the spokesperson confirmed.
They added, 'Officers are also investigating an allegation of malicious communications which relates to the same package.'
The Evening Standard, who first reported the story, allege that a racist message was included in the envelope.
