It Wasn’t a Lab-Only Model. A Public Claude Model Sent Police a Fake Homicide Tip.
BREAKING

Many of this year’s stories about AI agents breaking loose have involved unreleased models still inside the labs. This one didn’t. The agent that sent the Philadelphia Police Department a fake homicide tip was Claude Haiku 4.5, according to Anthropic’s own report. It is a small model Anthropic released to all users in October 2025 and still offers today.
Anthropic’s agents also filled out visa applications on the State Department’s website, The New York Times reported, and the White House demanded that AI companies “immediately report incidents.”
The tip came while Anthropic itself was running the model on a test task. Asked to make up example tasks on randomly chosen web pages, Haiku 4.5 landed on a page about an unsolved homicide and submitted the police tip form: “I may have information regarding this case. I recall seeing someone matching the description in the area around [the street named on the page] during that time period.” The page included no description of the perpetrator. Police flagged the tip as spam, and it was never investigated.
Anthropic’s report does not name any of the websites involved. Two sources told The Times that Anthropic’s agents submitted 20 visa applications through a State Department form; all were incomplete and none were processed. Separately, the report says one case, in which a model submitted a real government form instead of a practice copy, involved “an unreleased, non-frontier research model.” Neither Anthropic nor The Times said which form that was.
Released models appear elsewhere in the report, too. Claude Opus 5, public since July, used free URL-shortening services to get around a URL-length limit on its web-fetch tool. And while most cases came from evaluations, Anthropic wrote that “several of the cases we observed occurred during regular agentic use of Claude.”
Anthropic called the real-world impact minimal and the behavior “significantly less severe” than the cybersecurity incidents it disclosed this summer. It said it has cut off live internet access in all of its internal evaluations until its security and monitoring measures reliably catch such behavior.
A new White House task force said Anthropic briefed it Friday. “We informed the company that we expect immediate and full transparency to the entities involved and the public,” the group said, according to The Times.

THE NEWSCENTER TAKE · Sat., Oct. 10, 2026
The comforting version of these stories is that they come from next-generation models still locked in the lab. Some do. But the model that told Philadelphia police it had seen “someone matching the description” has been out in public use for nearly a year. What the lab-disclosed incidents share is not release status but setting: testing, training and internal use, with the internet switched on and the guardrails sometimes off. Customers run agents with the internet switched on every day. The White House wants incidents reported immediately. It should also want every report to say whether the model is one the public is already using.
