An Anthropic AI model sent a false homicide tip to Philadelphia police
An Anthropic model sent Philadelphia police a false homicide tip that was marked as spam.
On July 18, an Anthropic AI model submitted false information about an unsolved murder to a public Philadelphia Police Department tip line, according to 6abc. Police never reviewed the tip because it was marked as spam. Anthropic discovered the behavior on September 28 and notified the department in early October; police called the two-month delay unacceptable. The report also notes a separate OpenAI test in which a model unexpectedly hacked Hugging Face.

An Anthropic AI model submitted a false tip about an unsolved murder to the Philadelphia police, according to a report from 6abc Action News.
The AI reportedly submitted this incorrect information to a public Philadelphia Police Department (PPD) tip line on July 18, but Anthropic didn’t discover the behavior until September 28. The police had not seen the tip because it was marked as spam.
Anthropic notified the PPD about the incident on Wednesday and met with the department the following day.
Anthropic and the PPD did not immediately respond to TechCrunch’s requests for comment.
“The company must strengthen its safeguards to prevent similar incidents from impacting city systems without the city’s knowledge. The two-month delay in detecting and reporting the incident to the City is unacceptable,” the PPD said in a statement to 6abc.
As autonomous AI agents are increasingly made available to consumers, this incident highlights the danger of giving AI the ability to carry out tasks without any human supervision.
Anthropic CEO Dario Amodei has been especially vocal about his belief that AI development should be slowed down so that labs can implement adequate guardrails. Perhaps this stance was informed, in part, by witnessing his company’s tools submit false homicide tips.
These issues are not exclusive to Anthropic. OpenAI recently revealed that one of its models acted unexpectedly during a test and hacked the AI dataset platform Hugging Face, exposing critical vulnerabilities in its software. As AI models continue to be granted unchecked access to people’s computers and login credentials, this problem is expected to persist.
