A violent incident occurred in the bustling Dotonbori area of Osaka where three 17-year-old boys were stabbed, resulting in one death and another in critical condition. The suspect, Ryo Iwasaki, 21, was sent to prosecutors on murder charges; however, he refused to leave the detention center during the process. This led police to send only the necessary investigation documents to the Osaka District Prosecutor's Office. Police procedures dictate that suspects must either be sent to prosecutors with investigation documents or released within 48 hours of arrest, ensuring legal compliance in handling suspects.

Iwasaki had been cooperating with police interrogations until the day before his indictment. Reports indicate that he is accused of fatally stabbing Ryuunosuke Kamata, another 17-year-old, outside a building in Shinsaibashi around midnight. Following his arrest, Iwasaki claimed that he had no intention to kill and that he initially meant to use the knife for intimidation, but during an altercation with Kamata, he ended up stabbing him in the chest. Notably, he was found in possession of a folding knife that authorities believe was the weapon used in the crime.

Investigators are looking into the circumstances surrounding the incident, suggesting that it began with Iwasaki being admonished for inappropriate behavior towards a woman, which escalated into a confrontation with Kamata. The details from witnesses at the scene and the victim's injuries are critical as the investigation unfolds, shedding light on the motivations behind the stabbing and potential legal implications for Iwasaki as he faces serious charges.
