A bomb threat that triggered a major emergency response at a Pasadena hospital is believed to be connected to a group already known to law enforcement. Huntington Hospital has since reopened after authorities determined there was no immediate danger. The threat was received at about 5:40 a.m., prompting a large police presence and a search of the medical campus. A city spokesperson said the threat came from an extremist group familiar to investigators but did not identify the organization. Officials cleared the scene shortly before 9 a.m. after completing their investigation. During the incident, emergency patients were temporarily diverted to other hospitals to ensure public safety and prevent disruptions to critical care. Authorities have not announced any arrests or released additional details about the source of the threat. The investigation remains ongoing as law enforcement works to determine who was responsible and whether any criminal charges will be filed.
