All schools in Monterey Park have been placed on lockdown and East Los Angeles College has been evacuated after an anonymous caller threatened to "shoot up" an unknown campus Thursday morning, authorities said.
The shooting was supposed to happen at 8 a.m., the caller said.
Officers have been deployed to all Monterey Park schools and 10 campuses have been locked down.
Monterey Park police Chief Jim Smith said no gunman has been seen.
He cautioned: "It's really sketchy information."
A source familiar with the investigation said a caller on a cellphone threatened a shooting at a large school in Monterey Park. The call was routed through the California Highway Patrol and then the sheriff’s office.
A dispatcher with the CHP said it received a call about 7:14 a.m.
Authorities traced the call and found that the nearest campus to the caller was East Los Angeles College and sent the information to the L.A. County Sheriff’s Department. No specific campus was named in the threat, Monterey Park police said.
Numerous roads in the area have been closed.
