The Osaka District Public Prosecutor's Office has decided not to prosecute four men in their twenties who were arrested by the Osaka Prefectural Police for allegedly violating the Employment Security Law by introducing women for prostitution purposes. This decision was announced on the 13th. The arrests stemmed from a police search operation last July, which was aimed at uncovering related activities; however, the operation was marred by an incident where two officers from the investigative unit were accused of committing assault against a search target.

Following the initial arrests, the four suspects were released after the non-prosecution decision was made. Meanwhile, the officers involved in the assault were indicted for special public servant assault and received guilty verdicts. Additionally, the indictment process for the other involved parties was conducted while they remained at home, reflecting ongoing legal scrutiny into both the alleged violations of the Employment Security Law and the behavior of the police during the operation.

In January of this year, the Osaka Prefectural Police disciplined a total of 12 personnel in connection with this incident, which raises concerns about police conduct and accountability. When considering supervisory measures and guidance, a total of 35 personnel have faced disciplinary actions, highlighting attempts to address internal issues within law enforcement in response to the controversial incident during the enforcement of the law.
