London’s King Edward VII’s Hospital released a stern letter on Saturday admonishing an Australian media company for a radio prank that appears to have lead to a nurse’s death.

Jacintha Saldanha, 46, was one of two nurses tricked by a hoax call on Tuesday to glean intimate details about the condition of Kate, Duchess of Cambridge, who had been admitted to the hospital for acute morning sickness.

“To discover that, not only had this happened, but that the call had been pre-recorded and the decision to transmit approved by your station’s management, was truly appalling,” the hospital’s chairman Lord Glenarthur wrote in the letter.

“The immediate consequence of these premeditated and ill-considered actions was the humiliation of two dedicated and caring nurses who were simply doing their job tending to their patients.

“The longer term consequence has been reported around the world and is, frankly, tragic beyond words.”

Saldanha was found unconscious Friday morning at an address near the hospital, and paramedics pronounced her dead soon after.

Police said they considered the death unexplained, but they were not looking for anyone else, indicating the nurse had taken her own life.

Southern Cross Austereo (SCA) and the 2DayFM hosts Mel Greig and Michael Christian who made the hoax call have mutually decided to put the show on hold indefinitely.

“No one could reasonably foresee what actually happened in this case,” SCA chief executive Rhys Holleran said at a news conference on Saturday. “It’s incredibly tragic. Every one of us are deeply saddened. We’re incredibly sad for the family and that’s the focus.”

William and Kate, who left the hospital on Thursday, said they were “deeply saddened” by the death of Saldanha, who was married with two children.

“Their Royal Highnesses were looked after so wonderfully well at all times by everybody at King Edward VII’s Hospital, and their thoughts and prayers are with Jacintha Saldanha’s family, friends and colleagues at this very sad time,” a statement from William’s office said.
