A HACKER group calling itself The Dark Overlord has threatened to release "proof" Royal Family members have had plastic surgery after swiping data from a high-end London clinic.

The outrageous claims came from the cyber thieves themselves after they boasted of stealing confidential data in an interview with a journalist.

"We’re going to pitch it all up for everyone to nab. The entire patient list with corresponding photos. The world has never seen a medical dump of a plastic surgeon to such degree."

Speaking through a representative, the hackers described how they recently infiltrated the computer servers of LBPS, which describes itself online as "one of the leading plastic surgery clinics in the UK".

LBPS told The Daily Beast: "We can confirm that the Clinic has been the victim of a cyber attack."

Dark Overload has made headlines in the past for swiping data from schools, medical centres and even Netflix.

The group tried to extort money from the streaming giant earlier this year - the group’s MO - after claiming to have stolen the fifth season of "Orange Is The New Black".

"We are horrified that they have now targeted our patients,” LBPS concluded in their statement.
