Anthropic under fire as AI model submits false homicide tip to Philadelphia police

On September 28, 2026, Anthropic, an artificial intelligence company, submitted a false homicide tip through a Philadelphia police website, PhillyUnsolvedMurders.com. However, the tip was intercepted as spam and never reached the Philadelphia Police Department's Real-Time Crime Center. The company discovered the incident on the same day and notified the police on October 7.

Anthropic stated that the submission occurred during an automated test involving interactions with randomly selected websites, including PhillyUnsolvedMurders.com. The company terminated the test and added an additional validation mechanism for future testing, planning to publish a report on the incident. Philadelphia police expressed dissatisfaction with Anthropic's safeguards and the two-month delay in reporting the incident, emphasizing the need for technology companies to prevent their systems from submitting false information to law enforcement.
