Authorities are rushing to evacuate the Loma Linda Hospital in San Bernardino County following reports of a possible armed shooter.

Law enforcement was responding to reports of a possibly armed person at Loma Linda Hospital on Wednesday night. Armed officials were on the scene, working to clear out the facility. The San Bernardino County Sheriff’s Department is advising people to avoid the area and use alternative routes.

Investigators believe a Wednesday evening, March 12, call about an armed man in the children’s section of the Loma Linda University Medical Center that prompted evacuations and a response of 100-plus officers from across the region was a hoax, authorities said. There were no injuries, and no gunshots fired, they said.
