Hachioji, Tokyo: police say five high-school students assaulted a 17-year-old boy and demanded 150,000 yen, a figure they believe one of the group got from ChatGPT by asking about settlements for 'sexual harm to a child'
Sankei Shimbun reported on 10 June 2026, and NTV on 13-14 June, that the Tokyo Metropolitan Police Department's juvenile crimes division had arrested five high-school students on suspicion of injury and attempted extortion. According to the police account, late on 27 January 2026 a suspect who had previously dated a 17-year-old high-school boy invited him to a public square in Hachioji, where the group accused him of having touched her younger sister, assaulted him and broke his nose, and then told him to raise 150,000 yen, borrowing from his parents or friends if necessary. About ten people were present. Police believe the amount came from ChatGPT: one of them entered terms such as 'sexual harm to a child', and the chatbot displayed a minimum settlement of 150,000 yen. No payment is reported. Shukan Josei PRIME reports that four of the five admit the allegations and one partly denies them. The allegations are untested.
