Pippa Middleton has begun a High Court action for breach of privacy after personal photos were stolen by a computer hacker and offered for sale to The Sun.
The paper reported that a man demanded £50,000 for the images and data apparently taken from her iCloud account.
It said the man sent it two pictures of Middleton apparently taken at a wedding dress fitting.
Private messages were also said to be in the cache of data allegedly hacked by the man.
The Sun alerted Middleton and a spokesman told the paper: “Thank you very much for drawing this to the family’s attention.”
The man contacted The Sun via an encryption service and sought bids of at least £50,000 for the photos within 48 hours.
Middleton has lodged a case in the Queen’s Bench Division of the High Court against an un-named person.
A separate criminal investigation is underway.
