The boss of the parent company of the radio station behind a notorious royal prank call has come under fire after dismissing the outcome with the phrase “s**t happens”.

Police in London have contacted their Australian counterparts about speaking with the two radio presenters who made a prank phone call that led to the death of a nurse.

AUSTRALIAN authorities said yesterday a misunderstanding may have triggered a flight alert that forced a Los Angeles-bound plane to turn back to Sydney, in one of the country's worst airline scares since the September 11, 2001, attacks.
