After a series of embarrassing missteps — including multiple wrongful arrests — police investigating a high-profile cybercrime case Sunday took into custody a 30-year-old man previously convicted of a similar crime on suspicion of using hijacked computers to threaten murder.
Yusuke Katayama was convicted in an online-threat case in 2006 that investigators believe matches information shared by the self-proclaimed perpetrator in the current case, which also involves threats posted between last June and September.
Observers, however, have pointed out inconsistencies that must be addressed by police whose highly publicized mistakes — including the arrests of four innocent people in connection with the case — have cast doubt on their ability to investigate high-tech crime.
