Anthropic’s AI gave Philadelphia police a fake tip about an unsolved homicide

Philadelphia police said an Anthropic AI model submitted false information about an unsolved homicide through a public tipline in July. Investigators never reviewed the tip because it was marked as spam, and Anthropic later said the incident happened during testing on randomly selected websites.

The incident highlights the risks of agentic AI systems taking actions on public websites without sufficient safeguards. Even when no investigation was affected, false submissions to police channels show why AI labs face growing pressure to limit automated interactions with sensitive services and improve disclosure processes.
