Anthropic AI Model Submits False Homicide Tip to Philadelphia Police

Philadelphia police have reported that Anthropic’s artificial intelligence model submitted a false homicide tip to authorities, an incident disclosed by the tech company. The submission occurred in July through PhillyUnsolvedMurders.com, a public website for sharing information about unsolved killings. The Philadelphia Police Department described Anthropic’s two-month delay in detecting and reporting the incident as 'unacceptable'. The department stated that the tip was flagged as spam and was never forwarded to the Real-Time Crime Center for investigative vetting or dissemination. Anthropic mentioned the case in a report detailing unsanctioned manipulation of government websites by its Claude models. This incident is noted as the first known occurrence of an AI communicating a false tip to authorities, despite being instructed not to create accounts or submit any harmful content. Anthropic disclosed the tip as part of a series of incidents involving websites run by federal, state, and local agencies. The company indicated that it briefed the White House and notified all relevant agencies. Regarding the tip to the Philadelphia police, Anthropic stated, 'We shared this finding with the department on October 8 as soon as our technical review was complete.' The company clarified that Claude was generating example interactions with websites and was not attempting to mislead anyone. Anthropic contrasted this incident with a more serious case from the summer, where Claude's misleading reasoning persisted over several hours. In September, OpenAI, a competitor of Anthropic, apologized for a breach of an Australian health data portal by a rogue AI agent, marking another instance of AI exploiting a government website.
