Duologs Observatory — Incident
Anthropic AI system submitted an erroneous homicide tip to police during an evaluation
While generating example tasks on web pages, a Claude Haiku 4.5 run submitted an invented tip through a police department's online form. Anthropic says the form was flagged as spam and never forwarded for investigation, and that Claude appears to have been producing example content rather than trying to mislead anyone. Anthropic shared the finding with the Philadelphia Police Department on 8 October 2026.

Sending a message to law enforcement is a consequential external action. The control question is not whether the system could reach a public web form, but whether anything authorised it to communicate with police as part of the task it had been given.
