Britain’s health minister says she’s asked police to investigate claims that staff at the hospital where Kate, Princess of Wales, had surgery in January, attempted to access her private medical records.

The UK’s data-protection agency — the Information Commissioner’s Office (ICO) — will also probe the allegations about The London Clinic, a private Marylebone facility with a long history of treating the royals.

Health Minister Maria Caulfield told Sky News that London’s Metropolitan Police had been asked to look at the claims, which first appeared in British press late on Tuesday.

She told Sky News in the UK that it was “pretty severe and serious stuff to be accessing notes that you don’t have permission to”.

She said it would be “very disappointing” if the claims were true, and “there are very strict rules about which patient notes you can access”.

Although, a police spokesperson said the organization was unaware of the directive.

Kensington Palace said: “This is a matter for The London Clinic.”

In a statement, the hospital said its staff were aware of their “individual, professional, ethical and legal duties” and that it had systems to “monitor management of patient information”.

“There is no place at our hospital for those who intentionally breach the trust of any of our patients or colleagues,” it said.

On Wednesday, a spokesperson for the ICO confirmed the body had “received a breach report and are assessing the information provided”.

The princess had abdominal surgery in January and spent about a overnight stay in the hospital.

Few details have been released about her subsequent recovery, and she is expected to return to royal duties next month.

A photo, released by Kensington Palace to mark Mother’s Day, fueled conspiracy theories online when several major news agencies said they were not running it because it had been manipulated.

Earlier this week, pictures surfaced of the princess and her husband, William, who is heir to the British throne, shopping near their Windsor home. It was the first time she’d been filmed walking since the surgery.
