British police may want to speak to two Australian DJs following the death of the nurse who answered their prank call to the Duchess of Cambridge's hospital.
The Australian authorities confirmed they have had contact from the Met Police concerning 2Day FM presenters Michael Christian and Mel Greig.
The pair hoaxed King Edward VII's hospital staff where the pregnant Duchess was treated for extreme morning sickness.
Jacintha Saldanha - the nurse who took the call and put it through to colleague who divulged private information about Kate's treatment - was found dead on Friday.
New South Wales Police Deputy Commissioner Nick Kaldas said Scotland Yard had been in touch - but emphasized there was no suggestion that a crime had been committed.
He said: "There has been a request for assistance from London's Metropolitan Police to the New South Wales Police through the Australian Federal Police.
"The request has gone to the city central command - the area where the 2Day FM office is.
The company which owns the Australian radio station has called an emergency meeting to discuss the DJs' future.
Mr Kaldas added: "I have to stress, it hasn't been indicated to us that an offence has occurred, they haven't actually asked for anything yet - they've simply touched base, let us know of their interest and they'll get back to us if they want something done.
"Nothing has been requested of us yet."
Scotland Yard confirmed contact had been made with the authorities in Australia but did not elaborate further.
Meanwhile, Ms Saldanha's family in the UK and India have been paying tribute to the mother of two teenagers.
Her daughter Lisha wrote on Facebook, "I miss you, I love you", while her husband Ben Barboza has set up a tribute page on the social networking site.
He 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."
In India, her sister-in-law Celin D'Souza said: "I will really miss her a lot. She was a good-natured sister-in-law. I cannot forget her, she was so good."
The hospital where Ms Saldanha worked has condemned the stunt as "truly appalling" while a prominent Conservative MP has called for the DJs to be sacked.
In a letter to the Australian radio station 2Day FM's parent company, Lord Glenarthur, Chairman of King Edward VII's Hospital, said he wanted to "protest" against the "extremely foolish" gag.
The letter to Southern Cross Austereo said the immediate consequence of the station's "premeditated and ill-considered actions" led to the "humiliation" of Ms Saldanha and another nurse.
"The longer term consequence has been reported around the world and is, frankly, tragic beyond words," it added.
Tory MP Conor Burns, a member of the Culture, Media and Sport Select Committee, said: "The presenters should lose their jobs and there needs to be a serious review as to what they regard as entertainment and what is inappropriate."
News of the nurse's death has led to a huge backlash against the two presenters, Mel Greig and Michael Christian, who pretended to be the Queen and Prince Charles during the prank on their 2Day FM show.
Southern Cross Austereo said the pair are being "babysat" and kept away from hostile media coverage.
Spokeswoman Sandy Kaye said: "We're seriously concerned about their welfare and we’re doing whatever we can to help them."
The Duke of Cambridge made no comment on the situation as he attended a charity function in London on Saturday night without Kate - who is resting after her three day stay in hospital.
