On 19 July the Noda City department of the Chiba Prefectural Police announced the arrest of 49-year-old elementary school teacher Masaki Yabusaki on charges of intimidation.
The suspect had allegedly sent around half a dozens emails to the Noda Board of Education with oddly-worded threatening remarks such as “I will blow up bad guys and their government buildings” if they didn’t rescind a decision to extend the school week to include Saturday classes introduced this year.
