A man arrested in connection with a rampage Sunday that killed seven people in Japan's popular Akihabara electronics district allegedly posted messages on the Internet warning of such events, according to news reports.
Tomohiro Kato, 25, was arrested on suspicion of driving a two-ton, rented truck into the crowded Akihabara district, then jumping out and stabbing 17 bystanders, according to the Associated Press.
In the hours prior to the rampage, Kato allegedly posted dozens of warnings on the Internet. A Reuters report that cited Japanese newspapers included these alleged messages from Kato:
"I will kill people in Akihabara."
"I will crash my car and when the car becomes unusable, I will use a knife. Good-bye, everyone!," the Asahi newspaper reported.
"I'm used to acting like a good person. I can fool everyone easily," the Mainichi newspaper reported.
Kato allegedly used a cell phone to post his messages to an Internet bulletin board, according to the Associated Press.
The motive for the killing spree is still under investigation, according to press reports.
