British prosecutors said Friday they will not press charges against two Australian DJs over the royal hoax call that preceded a nurse's suicide.

Two Australian DJs impersonated Queen Elizabeth and her son, Prince Charles, as they phoned London's King Edward VII hospital in December to ask about the condition of the Duchess of Cambridge, formerly Kate Middleton, who had been hospitalized for treatment of acute morning sickness stemming from her pregnancy.

Nurse Jacintha Saldanha, who put the call through to a colleague who in turn described the details of Kate's condition, was found hanged in her room three days after the prank was broadcast across the world.

Prosecutors on Friday said there was no evidence to support a charge of manslaughter, and despite "some evidence" to warrant further investigation of offences under Britain's Data Protection Act and Malicious Communications Act, any potential prosecution would not be in the public interest.

'Harmless prank'

The Crown Prosecution Service said that decision was taken because it isn't possible to extradite from Australia for those potential offences, and because "however misguided, the telephone call was intended as a harmless prank."

DJs Michael Christian and Mel Greig —apologized after Saldanha's death in emotional interviews on Australian television, saying they never expected their call would be put through.

The radio show behind the call, the "Hot 30" program, was taken off the air following Saldanha's death.
