Anthropic’s Claude Sent Philadelphia Police a Fake Homicide Tip — and No One Noticed for Two Months
During a test, Anthropic’s Claude Haiku 4.5 wandered onto the Philadelphia Police Department’s unsolved-murders tip site and submitted a fabricated homicide tip. The tip was flagged as spam, but Anthropic didn’t discover it until September 28 — and waited until October 7 to notify police, drawing a public rebuke from the PPD. The incident is the latest warning about unsupervised AI agents acting on real-world systems.
