The joint investigation team of the Metropolitan Police Department and the police of Kanagawa, Osaka and Mie prefectures on Feb. 10 arrested Mr. Yusuke Katayama, a 30-year-old man from Koto Ward, Tokyo, on suspicion of making anonymous online threats in 2012 by remotely manipulating other people's personal computers.
Although a suspect has been arrested, the case poses serious questions for the nation's police: Do they have sufficient capability to solve cybercrimes in general and can they carry out an investigation against the suspect in a fair manner?
In this case, the police first arrested four men. Although all four suspects were eventually released without being indicted, two of them made "confessions." Considering that the men were innocent, this suggests that investigators used coercion or leading questions while interrogating them.
