The Federal Bureau of Investigation (FBI) is just one of several agencies investigating a bomb threat at San Gabriel Elementary School in Atascadero. The campus was shut down Friday morning and the surrounding neighborhood evacuated, according to police.
In addition to the FBI, the Atascadero Police Department, County of San Luis Obispo Hazardous Materials Team, San Luis Obispo Sheriff’s Department, California Highway Patrol, California State Parks Department, Atascadero State Hospital Police, San Luis Obispo Probation Department, and the San Luis Obispo District Attorney’s Office responded to assist.
Atascadero Police say threatening letters had been delivered to the school and a "suspicious object" was located on campus near the playground. Multiple agencies swept and secured the campus throughout the day.
"The incident appears to be isolated to the San Gabriel School campus and no ongoing threat has been identified," Atascadero Police said in a media statement.
Because of the ongoing nature of the investigation, specific details were not immediately being released by the agencies involved.
