Fullerton police are investigating bomb threats at four local schools and St. Jude Medical Center, prompting evacuations and lockdowns while authorities assess the credibility of the threats

Fullerton police are investigating bomb threats made at four local schools and St. Jude Medical Center on Thursday afternoon. The schools targeted include Sunny Hill High, Fullerton Union High, Troy High, and Fern Drive Elementary. 

As a precaution, all four schools were placed on lockdown while police worked to verify the legitimacy of the threats. At Fern Drive Elementary, officers stayed on campus with students and staff, while parents were advised to follow evacuation protocols set by the district. 

In a separate incident, a bomb threat prompted the evacuation of the emergency room at St. Jude Medical Center around 5:40 p.m. The evacuation lasted about 20 minutes before patients were allowed to return to the facility, according to Fullerton PD.

At this time, the credibility of the threats remains unclear, and no injuries have been reported during the investigations.
