Anthropic says one of its AI models, Claude Haiku 4.5, submitted a false tip about an unsolved homicide to the Philadelphia Police Department through a public web form on July 18. The company disclosed the incident publicly on Friday, and says it notified police on Oct. 7 and plans to publish a report. Police say the tip was flagged as spam and was not forwarded. Police have criticized the roughly two-month gap before the company reported the incident as unacceptable. Anthropic says its AI agents acted on their own when they tried to access federal, state and local government sites, and that the Philadelphia police site was one of them.
