Mother-of-two Jacintha Saldanha was found dead in her nurses' quarters three days after she transferred the call from the DJs to a colleague at London's King Edward VII's Hospital who then described Kate's condition in detail.
The 46-year-old, from Bristol, left two notes in her room and had marks on her wrist when her body was discovered on December 7 last year, Westminster Coroner's Court in London heard.
This morning we have learned that the Crown Prosecution Service has issued a statement regarding hoax calls to our hospital.
We have no further comment on this matter.
The consequences of that hoax call are well known, and tragic.
We will continue to support the family of much-loved nurse Jacintha Saldanha during what continues to be a very sad time.
Mel Greig said Jacintha Saldanha's death did not "seem real because you just couldn't foresee something like that happening from a prank call", in her first interview following the tragedy.
She told Australian network Channel 7: "You know it was never meant to go that far. It was meant to be a silly little prank that so many people have done before. This wasn't meant to happen."
- Australian DJs Mel Greig and Michael Christian made the hoax call to the King Edward VII's hospital in central London posing as the Queen and Prince of Wales when Kate was being treated for a rare form of pregnancy sickness.
- Nurse Jacintha Saldanha, who transferred them to a colleague, who then described Kate's condition in detail, was found hanged a few days after the incident.
- The DJs at the centre of the royal hoax said they were "heartbroken" at the death of nurse Ms Saldanha and wanted to say "sorry" to the family for the prank, in their first interview since the incident.
In reaching this decision, the CPS has taken into account the following, among other, matters:
It is not possible to extradite individuals from Australia in respect of the potential offences in question.
However misguided, the telephone call was intended as a harmless prank.
The consequences in this case were very sad.
We send our sincere condolences to Jacintha Saldanha’s family.
No charges will be brought against Australian DJs Mel Greig and Michael Christian over hoax calls to the hospital treating the Duchess of Cambridge for severe morning sickness, the Crown Prosecution Service said.
Scotland Yard has submitted a file to the Crown Prosecution Service relating to the prank call made to the hospital where the Duchess of Cambridge was treated for morning sickness.
Nurse Jacintha Saldanha, who worked at King Edward VII Hospital, was found hanged after she transferred the call from two Australian DJs to a colleague, who then described Kate's condition in detail.
The Crown Prosecution Service will now consider whether any potential offences may have been committed by making the hoax call.
