The two Australian DJs who pulled the prank call on the U.K. hospital where Kate Middleton was staying are now in hiding and may soon have to face police after the death of a nurse caught in the hoax.
This morning, there are also new questions about whether DJs Mel Greig and Michael Christian, radio shock jocks at Sydney's 2Day FM broke laws after they recorded the private conversation when they pretended to be Queen Elizabeth and Prince Charles.
British police have also contacted Australian police about a possible probe into the prank call, The Associated Press reported Sunday.
Rhys Holleran, CEO of Southern Cross Austereo, the parent company of Sydney's 2Day FM radio station said no laws were broken.
The prank had been cleared by the Australian radio station's lawyers. Holleran said the DJs followed the company's procedures before broadcasting the call.
"I think the more important question here is that we're very confident that we haven't done anything illegal. Our main concern at this point in time is what has happened is incredibly tragic and we're deeply saddened and we're incredibly affected by that," Holleran said Saturday.
The hoax has caused public outcry after the death of a nurse, Jacintha Saldanha, who connected the pair to the Duchess' room.
Saldanha was found dead Friday morning after police were called to an address near the hospital to "reports of a woman found unconscious," according to a statement from Scotland Yard.
Circumstances of her death are still being investigated, but are not suspicious at this stage, authorities said earlier.
Lord Glenarthur, the chairman of King Edward VII's Hospital, the U.K. hospital where the Duchess of Cambridge was receiving treatment, condemned the prank Saturday in a letter to the Max Moore-Wilton, chairman of Southern Cross Austereo, the Australian radio station's parent company.
Glenarthur said the prank humiliated "two dedicated and caring nurses," and the consequences were "tragic beyond words," The Associated Press reported.
Max Moore-Wilton, the chairman of Southern Cross Austereo, said in a letter to Lord Glenarthur Sunday that the company is reviewing the station's broadcast policies, the AP reported.
"I can assure you we are taking immediate action and reviewing the broadcast and processes involved," Moore-Wilton said in the letter. "As we have said in our own statements on the matter, the outcome was unforeseeable and very regrettable."
Saldanha came to England from India nine years ago, with her husband and two children.
On Facebook, her 14-year-old daughter wrote this weekend, simply: "I miss you, I loveeee you."
Saldanha worked as a nurse at King Edward VII private hospital for four years. Her family lives 100 miles away in Bristol, but while on shift she slept in a residence for nurses.
With no receptionist on duty overnight she answered the prank call and put it through.
The hospital called her a "first-class nurse" and "a well-respected and popular member of the staff" and extended "deepest sympathies" to family and friends, saying that "everyone is shocked" at this "tragic event."
The duchess spent three days at the hospital undergoing treatment for hyperemesis gravidarum, severe or debilitating nausea and vomiting. She was released from the hospital Thursday morning.
The hospital apologized for the mistake.
"The call was transferred through to a ward, and a short conversation was held with one of the nursing staff," the hospital said in a statement. "King Edward VII's Hospital deeply regrets this incident."
The radio station also apologized for the prank call.
"2Day FM sincerely apologizes for any inconvenience caused by the inquiry to Kate's hospital. The radio segment was done with lighthearted intentions," the station said in a statement earlier.
DJs in Hiding
Greig and Christian are said to be in a fragile emotional state since Saldanha was found dead on Friday.
Station executives said the hosts are seeking the help of counselors.
"These people aren't machines, they're human beings," Holleran told reporters on Saturday. "We're all affected by this."
The DJs are in hiding and their Facebook and twitter accounts are now dark.
The Sydney radio station -- famous for its pranks and outrageousness -- has suspended all advertising in the face an advertising boycott and Greig and Christian have been pulled off the air.
Last spring, the station was warned by Australia's broadcast regulator about violations of the "decency provision" of the country's broadcast code.
Night Out Without Kate
Prince William was on his own Saturday night at a charity ball, for his first public function since his wife's pregnancy was announced.
In conversation he quipped about his Kate's illness: "I don't know why they call it morning sickness -- they should call it all day and all night sickness."
He did not talk about the tragic death of the nurse who fell victim to the hoax call, but he and Kate have issued a statement of sympathy for the family.
"The Duke and Duchess of Cambridge are deeply saddened to learn of the death of Jacintha Saldanha," a spokesman from St. James Palace said in a statement.
For Kate, it is yet another test of her new life as a very public royal. In September, a tabloid photographer using an extremely long lens photographed her topless on a private vacation.
"While she understood what she was taking on, there have been a couple of things that will have made them go oh my goodness and think we didn't think it would be that bad in this day and age," said Victoria Murphy, royal reporter with The Daily Mirror.
