School principal arrested for sending threatening emails to former student

Saitama police on Sunday searched the office of a high school principal and confiscated two computers after he was arrested for allegedly sending threatening messages by email to a former student. The suspect, Kazuo Ichikawa, 56, was arrested during Saturday's graduation ceremony.
Ichikawa began an acquaintance with her around January 2002, when he served as the assistant principal of another high school. She was a student there, according to police.
In March last year, she proposed to end the relationship, and he is suspected of sending more than 10 threatening emails to her between late November and mid-December in order to persuade her to continue their relationship, they said.
He noted in them, "I don't care about what will happen to you. I can kill somebody in cold blood," and in another one stating, "I will expose your private life," according to the police.
He has denied the charges, telling investigators, "I didn't intend to threaten her," according to police.
Police launched an investigation into the case after receiving reports from the woman's family.
