Tokyo Metropolitan Police arrested a 27 year old woman for threatening Oda Eiichiro (the author of "One Piece"). According to the police, she had a grudge against Oda because he fired her husband, and she sent threatening e-mails (like "Should Die") about 100 times to his cell phone for four months in 2007.
