The Guardian clearly suggests in their piece that the just-arrested News of the World Hollywood correspondent sure got a lot of uncannily accurate secret scoops on the stars in his time. The Guardian:
His move to the US makes his arrest, the 13th made by Operation Weeting, particularly significant. If Desborough was involved in hacking while in Britain, as police appear to believe he was, it raises the question of whether he practised those techniques in the US – and if so, whether he was the first and only News of the World journalist in the US to do so.There's clearly no evidence that we know of pointing to any wrongdoing in the US. But it would be naive of US authorities to not consider the possibility.
