UPDATE (1:09 P.M.) - Santa Barbara County Sheriff's officers determined the report of an active shooter at San Marcos High School to be a "swatting" call.
Deputies, along with CHP officers, responded to the campus around 10:26 a.m. Monday while Santa Barbara County Fire and American Medical Response staged in the area, officials said.
Soon after deputies arrived on the scene, they suspect that this was a "swatting" incident. However, in an abundance of caution, officials said students and staff at the school were still asked to shelter in place while law enforcement conducted a room-by-room search of the campus.
Officers did not find any injured persons or shooters during the hoax and determined the report to be a hoax, according to the press release.
The shelter-in-place was lifted at 11:15 a.m.
Officers said they are working to identify the individual responsible for the swatting call and bring them to justice.
The Sheriff's Office is reminding the public that swatting calls are not only illegal, but they put the lives of innocent people at risk.
