A 31-year-old man indicted for remotely operating other people's personal computers to issue a bomb threat, as well as threatening other violent attacks in 2012, was released Wednesday on bail following 13 months in detention.
After initially approving bail for Yusuke Katayama on Tuesday, the Tokyo High Court suspended the decision in the face of prosecutors' motion for complaint. But the court decided Wednesday to release him as it found the complaint was lodged by a prosecutor not authorized to do so.
After the release, Katayama told reporters, "I am innocent. My arrest was a bolt from the blue. I was also a victim of remote control."
The prosecutors maintain that Katayama, who has been in custody for about 13 months since his arrest in February last year, used Internet message boards to infect PCs with viruses enabling him to control them remotely and send e-mail threats, including a bomb threat that forced a New York-bound Japan Airlines flight to return to Narita airport.
Katayama pleaded not guilty during the first court hearing last month and sought release on bail.
Before his arrest, police wrongly arrested four other people whose computers were remotely used to issue threats by e-mail.
