# Why the media is unable to report on a case that has generated huge interest online #
> A very high-profile figure was convicted on Tuesday of a serious crime, but we are unable to report their identity due to a suppression order.
> The person, whose case has attracted significant media attention, was convicted on the second attempt, after the jury in an earlier trial was unable to reach a verdict. They will be remanded when they return to court in February for sentencing.
