Incident 17515 Report
Anthropic AI Agent Reportedly Submitted a Fabricated Homicide Tip to Police in Philadelphia

2026-07-18

During an evaluation by AI developer Anthropic, a Claude Haiku 4.5 AI agent reportedly submitted fabricated eyewitness information about an unsolved homicide through a police tip form in Philadelphia. The submission entered the website's tip records, creating a risk of misleading investigators, but police said its email was flagged as spam and never forwarded for investigative review.
