The Buenos Aires Herald reports that Argentine Federal Police detained a 15-year-old on Thursday after the FBI flagged his ChatGPT conversations. According to the Herald, the investigation started on 19 August with an alert from the FBI Legal Attache at the US Embassy in Argentina, raised after the teenager used monitored terms while asking the chatbot what he would need to carry out an attack on classmates, planned for 2027. He was identified through his IP address and lives in Quilmes, in Buenos Aires province. No firearms or ammunition were found at his home during the arrest, and local law means officials have not released his identity. It is a concrete look at what chatbot safety monitoring actually does once it leaves the lab.
