Argentine Federal Police raided the home of a 15-year-old in Quilmes on September 11, 2026 after the FBI alerted them that the teen had used ChatGPT to discuss plans for a school shooting targeting former classmates in 2027. The investigation began August 19 after monitored keywords in the teen’s chatbot conversations triggered an FBI alert to the U.S. Embassy in Argentina, and authorities identified the suspect via those keywords and his IP address. Officers seized tactical gear and phones during the raid, and the teen was charged with public intimidation, part of what local prosecutors describe as a broader rise in online threat cases.
