The National Police Agency (NPA) was embarrassed after it emerged that officers had extracted "confessions" from four people who had nothing to do with the threats.

An anonymous hacker then sent messages to newspapers and broadcasters last month, with the sender claiming details of a used to dispatch the threats were strapped to a cat living on an island near Tokyo.

After cracking a set of riddles, police found the cat and removed a card from its collar which revealed a message saying "a past experience in a " had caused the hacker to act.

The message said the case "changed" the anonymous hacker's life, and added that "no more messages will be sent" local media reported.

This reads like a script from a prime-time television crime drama. I really hope it doesn't turn out that the cat set him up. I have been online for years, this site included, with various cats sitting on my lap night after night. I'm not sure what they pick up on.

That being said, I admit I do not recall making many of the comments attributed to me on phys.org. I am typing this now only because they are all asleep at the moment. I am alone. I am going to check for a key-logger as soon as I post this.
