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.
