When I see this question I think of the Peter Wright situation. As soon as the press got ahold of this the Australian police had raided his house. I do not know all of the specifics but that is a pretty quick reaction by the police. This could be an isolated situation.
I think you are think of Craig Wright, and he was wanted on tax "issues" long before that wired article broke. I suppose that story release may have helped move the raid up as once he was in the spotlight he might have tried to run or something, but Bitcoin was not the sole source of his trouble with the law..
