Montebello High School and Montebello Area Intermediate School were placed on lockdown Wednesday afternoon as authorities tried to apprehend a murder suspect in the area, authorities said.

The suspect was seen running through a residential neighborhood near West Cleveland Avenue and North Concourse Avenue, according to Sky5 reporter Gil Leyvas.

A large police perimeter encompassed several city blocks and both campuses.

Students were eventually sent home as the Los Angeles County Sheriff’s Department continued with a “focused search” for the suspect, the City of Montebello said.

No further information about the suspect was released.

Montebello is located ten miles east of Downtown Los Angeles.
