Japan: Killer of seven gave online warning of Tokyo rampage

The 25-year-old man arrested for stabbing seven people to death on a Tokyo street had warned that he was about to kill in a series of messages he sent to an online noticeboard, some posted minutes before he went on the rampage.

In the first post at 5.21am on Sunday, on a thread entitled "I will kill people in Akihabara", Tomohiro Kato wrote: "I will crash my car, and if it is destroyed, I'll use a knife. Goodbye, everyone."
