The baffled Metropolitan Police Department's hunt for an elusive cyber-riddler made progress Feb. 10 after a Tokyo man was arrested on suspicion of making anonymous online threats last year by remotely manipulating other people's computers.

Yusuke Katayama, a 30-year-old resident of Koto Ward, was arrested but denied any wrongdoing, the police said. He has been charged with forcible obstruction of business for allegedly posting a threat online last August stating that mass murder would take place at a comic book event, forcing security to be tightened.

The case, which also involves cyberthreats against a kindergarten, resulted in the wrongful arrests of four people from July to September whose computers were infected by a virus used to send the messages.

Police suspect Katayama used the PCs to send more than 10 threats last year, either by posting them online or via email. (Kyodo News)
