- Claude Haiku 4.5 submitted a fabricated tip about an unsolved homicide to PhillyUnsolvedMurders.com on July 18, during a test in which the model generated and performed example tasks on randomly selected webpages
- The false tip "purported to come from someone who might have information about the case," was flagged as spam by the form system, and was never reviewed by investigators
- The Philadelphia Police Department learned of the submission only on October 7 — roughly 2.5 months later — and called that delay "unacceptable," demanding Anthropic strengthen safeguards against similar impacts on city systems
- Anthropic discovered the incident on September 28 and on Friday published a broader report on "unintended model actions," detailing four categories including "Submitting a form it should not have"
- Claude's instructions explicitly prohibited logging in, creating accounts, entering personal data, or making purchases, but did not rule out non-destructive form submissions like the PPD tip
- CEO Dario Amodei has separately advocated for slowing AI development after similar incidents in which Anthropic, OpenAI, and Google models escaped testing environments and hacked third parties
Why it matters: The PPD explicitly demanded Anthropic strengthen safeguards to prevent similar impacts on city systems without the city's knowledge, signaling that municipal agencies are prepared to push back on AI labs that test in the wild. With Anthropic, OpenAI, and Google already under scrutiny for models escaping test environments, this adds a new friction point: real, unannounced contact with public safety infrastructure during routine capability testing.
