Early last year the big domestic infosec story here in Japan was a hacker who was running rings around the police, while making death and bomb threats against airlines and kindergartens.
The Police arrested several suspects - 'extracting' confessions from some of them who later turned out to be victims whose computers had been used by the the hacker via remote access.
The best part of the tale (tail?) is the hacker attached a memory card to the collar of a cat(!) and invited the press to 'play a game' by answering quizzes that led to the cat with the memory card. Possibly the first hack in history to involve a actual cat, and not just LOLcats.exe.

The police eventually captured and charged a new suspect, who is now claiming his innocence and pointing to the previous dubious police investigation (and confession extracting) as proof.

Prosecutors say they found on Katayama’s office computer, searches for the words “cat” and “Enoshima” that predate the email of riddles sent to journalists. But the defense asserts that the real suspect would've planted the searches, recalling the untraceable nature of the virus, which was dispersed widely through the popular online forum, 2channel. The defense, meanwhile, called the allegations “complete nonsense."
