CU Boulder Evacuates Three Buildings Amid Unconfirmed Bomb Threat

The University of Colorado Boulder evacuated three buildings—Norlin Library, Ketchum Arts and Sciences, and Ramaley Biology—due to an unconfirmed bomb threat, prompting a campus emergency alert advising people to avoid the area. Police deployed K-9 units to investigate the threat, but it remains unconfirmed as authorities continue their investigation. This evacuation follows a recent series of security incidents in Boulder, including a swatting hoax at Norlin Library and a lockdown at nearby schools triggered by a misidentified individual. Police have not confirmed any connection between Friday's incident and earlier false reports. The situation is ongoing, and officials have asked the public to stay clear of the affected buildings until further notice. Multiple local news outlets are providing updates as the story develops.
