This study examined Japanese bomb threats by telephone and offender characteristics.
This study examined telephone bomb threats and offender characteristics in Japan (N = 101). The results showed that the most frequent offenders were middle-aged men (mean 42.6 years), motivated by desire for money (46 percent), resentment (26 percent), or diversion (24 percent). In the case of female offenders, most were connected with the targets (83 percent). Categorical principle component analysis and hierarchical cluster analysis differentiated the offenders into three themes. 'Instrumental' offenders telephoned the target directly (e.g. a bank or department store), demanding money by public phone. 'Expressive/affective' offenders motivated by resentment telephoned from their home and almost never had a criminal record. 'Expressive/cognitive' offenders motivated by diversion targeted railways and mostly telephoned emergency numbers. Tables, figures, references, and appendix (Published Abstract)
