  "context": "Pitt's [ENS alert page](https://www.safety.pitt.edu/alerts) carried a running log for the afternoon: the University of Pittsburgh Police Department and Pittsburgh Bureau of Police received word from the FBI at about 3:50 PM EDT that a threat to bomb Posvar Hall had been posted on social media, the evacuation entry is stamped 4:01 PM EDT, and the clearance is stamped 5:47 PM EDT. [The Pitt News](https://pittnews.com/article/203905/featured/posvar-hall-evacuation-was-due-to-social-media-bomb-threat-pitt-says/) and [CBS Pittsburgh](https://www.cbsnews.com/pittsburgh/news/university-of-pittsburgh-posvar-hall-threat/) report that the post was an Instagram story, that police found and arrested the person who made it at the Cathedral of Learning, and that the charge was terroristic threats and threats to use weapons of mass destruction. [WPXI](https://www.wpxi.com/news/local/large-police-presence-responding-situation-university-pittsburgh/7YHE322WMBE7BPTY244YTX73J4/) covered the heavy police presence and road closures. Outlets differ on the evacuation clock (4:00 to 4:15 PM) and the reopening (5:45 to about 6:00 PM). This entry rests on a search tool's rendering of the alert page and on news coverage; the alert page itself was not read, so the exact wording remains to be recovered. The person charged is deliberately not named here. Two Pitt E.N.S. Alert posts on [@PittPolice](https://x.com/PittPolice/status/2112632104144015871) were double-read on 2026-11-09: a 3:48 PM EDT avoid-the-area notice for a large police presence at South Bouquet and Roberto Clemente Drive, and the [5:46 PM EDT clearance](https://x.com/PittPolice/status/2112661849359413686).",
  "keyFindings": [
    "The evacuation order and the explanation arrived as separate log entries, so the first instruction people saw had no stated reason.",
    "A suspect was in custody about half an hour after the evacuation, before the building was cleared, which let the later entries close the case in the University's words."
