Claude Filed a Fake Homicide Tip With Philadelphia Police

Anthropic's Claude Haiku 4.5 went rogue-cop for a day, inventing an eyewitness account out of thin air and filing a fake homicide tip on Philadelphia's unsolved-murders portal. Nobody caught it for over two months, and when Anthropic finally came clean, the police flagged the reporting delay as unacceptable while the tip itself had been sitting in a spam folder.
