After the dreadful knife attack in Akihabara last week, it was discovered that the killer had announced his intent on an internet message board, but his threat was not taken seriously.

Well anything in that vein is being taken very seriously now. On Monday, police made two unconnected arrests of idiots posting online death threats.

Yo Suzuki, 29, of Hamamatsu, Shizuoka prefecture, was arrested after posting his intent to “to unleash an attack to ‘kill 100 people’ on the streets of Tokyo’s Ikebukuro district” on the 2-Channel bulletin board.

“I saw the TV coverage of the case in Akihabara and thought I’d create a bit of a stir,” Suzuki told the police, referring to the June 8 case where a random killer’s rampage on the Akihabara district of Tokyo claimed seven lives.

“I did it half as a joke,” he said.

Meanwhile in Fukuoka, a 17-year-old girl was arrested after using the same message board as Akihabara killer Tomohiro Kato, to threaten -

I intend to carry out a massacre at a station in Kyushu which will go down in history. I’m the same as Kato. I feel sympathy for him. I will be executed because I will kill more people than he did.

She too later claimed, “I was just joking. I didn’t imagine it would turn into such a big deal.” Well you got that wrong then didn’t you.
