San Bernardino County Sheriff's officials reported that on Tuesday morning, multiple agencies across the county received similar calls of threats on school grounds. The Barstow Police Department also reported a bomb threat at one school.
Sheriff's officials said each call had been a hoax; however, officers and detectives have remained on campuses conducting investigations.
The Sheriff's Department said they are aware of calls to area schools regarding reports of gunfire. Deputies have responded to all locations and have secured and cleared the schools.
Sheriff's spokeswoman Gloria Huerta told the Daily Press that the department did not receive any false reports for schools in Apple Valley, Hesperia, Victorville, or the rest of the Victor Valley.
Sheriff's Dispatch received calls reporting an active shooter at Alta Loma High School in Rancho Cucamonga and San Andreas High School in San Bernardino.
Deputies from the Rancho Cucamonga Station and Highland Station, as well as officers from San Bernardino Police and San Bernardino City Unified Police, immediately responded to their respective schools.
Both schools were secured, and a thorough search was conducted. All staff and students were safe, and the reports were determined to be false.
The investigation into the source of the calls is ongoing. Anyone with information about the Inland Empire investigations is asked by sheriff's officials to contact Sheriff's Dispatch at 909-387-8313 or 760- 956-5001.
Callers wishing to remain anonymous are urged to contact the We-Tip Hotline at 800-78CRIME (27463) or wetip.com.
