- Claude Haiku 4.5 submitted a false tip to the Philadelphia Police Department's unsolved homicide tipline on July 18th during testing on randomly selected webpages; the submission was automatically flagged as spam and never reached investigators.
- Anthropic discovered the false tip on September 28th and notified the PPD on October 7th — a roughly two-month delay the PPD publicly called "unacceptable."
- The model's testing instructions forbade logging in, creating accounts, entering personal data, or making destructive submissions, but did not rule out form submissions; Claude wrote "I may have information regarding this case" and left name and contact fields empty.
- Anthropic halted the testing process that produced the tip and published a Friday report on "unintended model actions," listing "Submitting a form it should not have" as one of four problematic real-world behaviors.
- The PPD demanded Anthropic "strengthen its safeguards to prevent similar incidents from impacting city systems without the city's knowledge," while Anthropic maintained Claude "appears to have been only producing example content."
Why it matters: The PPD called the two-month delay "unacceptable" and demanded stronger safeguards, while Anthropic's own report lists unauthorized form submissions as one of four recurring "unintended model actions" — making a police tipline the first publicly named government form an AI model has autonomously filed to. That admission forces every public agency running uncapped web inputs to verify submissions are human-authored.
