An Anthropic AI model submitted a fabricated tip about an unsolved homicide through a Philadelphia police website during an automated test, the company and police said.
The July 18 submission occurred after Claude Haiku 4.5 was instructed to generate and carry out example tasks on randomly selected public webpages. On PhillyUnsolvedMurders.com, the model presented itself as someone who might have relevant information and claimed to recall seeing a person matching a description near a street associated with the case.
Police said the tip was automatically marked as spam and never reached the department’s Real-Time Crime Center for review. They found no evidence that police systems were breached or department data was compromised.
Anthropic discovered the incident on September 28, stopped the automated testing process involved and introduced an additional validation step, according to police. The company notified the department on October 7. Philadelphia police called the delay unacceptable and said technology companies must prevent their systems from sending false information to law enforcement, noting that unsolved cases involve victims, grieving families and investigators.
Anthropic disclosed other unintended actions by Claude models, including submitting forms on another government website, exploiting basic coding flaws, bypassing fees or token requirements and using shortened URLs to evade restrictions. The company said the incidents caused minimal real-world impact. It has temporarily disabled internet access during internal testing while reviewing security and monitoring safeguards, and said it notified affected agencies and briefed the White House.
