The news of rocker Tom Petty's death swept through online news websites and social media this morning, Australian time, following reports from gossip site TMZ. Tributes were posted by celebs and prepared obituaries published. The problem, though, was that Petty was not actually dead -- he had a cardiac arrest and was taken to hospital, but he was still alive.

The death was reported by US network CBS -- a network that prides itself on its news coverage -- after the Los Angeles Police Department confirmed the news. CBS and Variety both reported the death early on, saying they had confirmed it with their sources.
