The owners of an Australian radio station at the centre of the royal prank call scandal Sunday said the tragic death of a nurse was "unforeseeable" and vowed to review its broadcasting processes.
Executives at Southern Cross Austereo, owners of 2Day FM, held an emergency meeting to consider a letter from Lord Simon Glenarthur, chairman of London's King Edward VII's Hospital, protesting the "appalling" hoax.
In his letter, Lord Glenarthur urged the company to ensure that such calls never happen again.
"It is too early to know the full details leading to this tragic event and we are anxious to review the results of any investigation that may be made available to us or made public," Southern Cross Austereo's reply said.
"We can assure you that we will be fully co-operative with all investigations," it added, according to Australian Associated Press.
"As we have said in our own statements on the matter, the outcome was unforeseeable and very regrettable. I can assure you we are taking immediate action and reviewing the broadcast and processes involved."
Britain has reacted with horror to the death of mother-of-two Jacintha Saldanha, 46, who is believed to have taken her own life after being duped by two 2Day FM presenters seeking news on the pregnancy of Prince William's wife Kate.
She was found dead on Friday, days after she answered a call at the hospital from hosts Mel Greig and Michael Christian, posing as Queen Elizabeth II and William's father, Prince Charles.
There was no receptionist on duty and Ms. Saldanha put them through to a colleague who divulged details of Kate's recovery from severe morning sickness.
The prank call was pre-recorded and vetted by lawyers before being broadcast to listeners in Sydney.
Australian newspapers said Ms. Greig and Mr. Christian face questioning by police after a request from Scotland Yard.
"But I have to stress it hasn't been indicated to us that an offence has occurred," New South Wales state deputy commissioner Nick Kaldas said.
"They have not asked for anything yet. They simply touched base and let us know of their interest and they will get back to us if they want anything done."
Ms. Greig and Mr. Christian have both apologized. Rhys Holleran, chief executive of Southern Cross Austereo, said they were "shattered" and undergoing counselling.
The nurse's death unleashed a torrent of online anger directed at the presenters who have been taken off air and are in hiding, while reports said advertisers have suspended their accounts with the broadcaster.
Flowers were placed on Saturday outside the nurses' accommodation block where Ms. Saldanha's body was discovered.
At the family home in Bristol, southwest England, relatives and friends gathered round to comfort Ms. Saldanha's husband, Benedict Barboza, and the couple's son and daughter, aged 14 and 16.
Reports said the family had moved from India around a decade ago.
In a message posted on his Facebook page, Barboza reportedly wrote: "I am devastated with the tragic loss of my beloved wife Jacintha in tragic circumstances, She will be laid to rest in Shirva, India."
Ms. Saldanha's sister-in-law, Irene D'Souza, told AFP by telephone from the town of Shirva, 400 kilometres from the southern Indian city of Bangalore, that she was due to visit them at Christmas.
"It is hard to believe Jacintha could commit suicide as she was not the type of woman to do it," Ms. D'Souza said.
The British press condemned the hoax on Sunday, while Australian media said it was not the time for "hysterical finger-pointing."
"Radio hosts Mel Greig and Michael Christian did not kill British nurse Jacintha Saldanha," said Sydney's Daily Telegraph in an editorial, hitting out at the "predictable British media frenzy."
"Suicide always leaves us looking for answers – and for someone to blame. Suicide is a complex act and can rarely be entirely blamed on a lone event, however distressing," it added.
While reports have referred to suicide, British police said the death remained unexplained ahead of a post-mortem.
