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.

A caller told deputies that they were going to "shoot up" the hospital and that they had a bomb, which was determined to be a hoax after an hours-long investigation on Wednesday.

An all-clear was declared at Loma Linda University Children's Hospital on Wednesday evening after a 'swatting' call reporting an armed man.
