A 35-year-old man was arrested in connection to the alleged hack of Pippa Middleton's iCloud account, the BBC reported. The news came just a day after police started an investigation based on reports that nearly 3,000 photos were stolen from the iCloud account of Kate Middleton's sister.

Officials investigating the case arrested the man in Northamptonshire in central England, London's Metropolitan Police Service reportedly said late Saturday. Met police said that the man was taken into custody on suspicion of an offense undrer the Computer Misuse Act.

Britain's Sun and Daily Mail newspapers reported that an anonymous seller contacted them and offered to sell the images for $65,000.

The hacker, who identified himself as “Crafty Cockney,” emailed two photos of Pippa and her fiancé, James Matthews, to the Sun to prove the authenticity of the photos. Pippa and Matthews got engaged in July and are set marry in 2017.

"This isnt (sic) an auction it will be a simple process of the highest bid," the seller reportedly said.

According to reports, some of the photos show Pippa at a wedding-dress fitting, while other images include private photos of the Duchess of Cambridge and her children, Prince George and Princess Charlotte.
