The manhunt for suspects involved in a series of robberies across multiple prefectures intensified. Early morning reports indicated a second suspect turned himself in for the Ichikawa, Chiba incident. Investigations revealed potential links to other crimes, including a murder in Yokohama. Law enforcement established a joint task force across four prefectures to identify the mastermind behind these "dark part-time job" schemes. The perpetrators used various online aliases for coordination, with over 30 account names identified. As the day progressed, arrests were made, including one in Tokyo's Kokubunji. The scope of the criminal network became clearer, with similar incidents reported in Hokkaido and Tochigi. By evening, discussions shifted to preventive measures, with JR West developing anti-knife umbrellas for train security.
