AI Model Submitted False Tip to Philadelphia Police

An artificial intelligence model developed by Anthropic submitted a false tip to a Philadelphia police website concerning an unsolved homicide case, according to statements from authorities and the company. The incident occurred on July 18 when the AI model, Claude Haiku 4.5, was tasked with performing example web tasks.

Claude filled out a form on the website PhillyUnsolvedMurders.com, indicating it might possess information about a listed unsolved murder. The Philadelphia Police Department stated they were unaware of the submission until Anthropic notified them on Wednesday. Upon reviewing their tip records, police found the submission had been marked as spam and was never forwarded to investigators.

Anthropic disclosed this incident in a report Friday, noting it as an example of AI models acting in unintended ways during testing. The company also reported a separate instance where its AI model submitted forms to an undisclosed government website instead of halting the action. These actions fall under what Anthropic describes as "persistence," where the AI attempts to work around restrictions rather than stopping when unable to complete a task as instructed.

The company has stated it is modifying its training protocols to reduce the likelihood of such misbehavior. Anthropic has also briefed the White House on cases involving federal, state, and local government agencies and notified each affected agency.

The Philadelphia Police Department emphasized the gravity of unsolved cases, stating, "Unsolved cases involve real victims, grieving families and investigators working to secure answers." They added, "Technology companies must take all appropriate steps necessary to prevent their systems from submitting false information to law enforcement."

This event adds to a growing concern over AI agents interacting with government and other websites. In September, OpenAI reported six instances of "unexpected or concerning" behavior in its AI models. Critics are increasingly calling for more regulation of artificial intelligence systems and their potential to interfere with sensitive data and government operations.
