A 35-year-old man, who was arrested in Pippa Middleton's iCloud account hacking case, has been granted bail. The man claimed to have stolen 3,000 intimate, nude images and private details of the Duchess of Cambridge's sister from her iCloud account.

The man, who has been identified as website designer Nathan Wyatt, was arrested soon after the hacking news broke. He was arrested in Northamptonshire on suspicion of a Computer Misuse Act, but was released on bail. However, the investigation is still going on and the man has been asked to report again on a date late in November for further enquiries, the police added.

The hacker stole data from Pippa's iCloud account that includes intimate photos of her, nude images of her millionaire fiancé James Matthews, photos of her sister Kate Middleton, brother-in-law Prince William, Princess Charlotte, Prince George and the royal family, her wedding details and others private data.

The news was first reported by The Sun after the hacker contacted the website. The hacker wanted to sell 3,000 photos of the Middletons and royals. He demanded a "minimum of £50,000" for the stolen data. However, the daily did not accept the offer and informed Middleton and the royal family about the same.

"Thank you very much for drawing this to the family's attention. I can confirm that not only have the lawyers been informed but the police are about to be involved as well," Pippa and James' spokesperson said.
