Claude submitted a false murder tip to Philadelphia police

Key points

• Claude Haiku 4.5 filled out and submitted a Philadelphia police unsolved-murder tip form on July 18 during Anthropic testing.
• Anthropic found the incident on September 28 and told police on October 8, a delay police called unacceptable.
• The tip was caught by a spam filter, had empty name and contact fields, and was never reviewed by a person.
• A New York Times report, citing anonymous sources, says Claude submitted 20 incomplete visa applications on the State Department website.

Why it matters for marketers: Content teams running AI agents on live web forms should restrict form submissions, since instructions alone did not stop unintended submissions.
