  • A neighborhood elementary school was placed on lockdown as a precaution
  • No evacuation orders were issued and no injuries were reported
  • Why it matters: The incident briefly raised safety concerns for families and students blocks away from the discovery

Deputies responded to the residential block after receiving a call about possible explosives. The LA County Sheriff’s Department confirmed to News Of Los Angeles that the devices were grenades and had been moved outside the home so arson explosive investigators could examine them.

Video from the scene shows a sizable law-enforcement presence, including vehicles from the department’s specialized bomb squad. Technicians wearing protective gear worked in the driveway and yard while deputies cordoned off the immediate area.

Authorities have not disclosed how many grenades were found, who lives at the property, or why the explosives were there. The sheriff’s department said the investigation is active and ongoing.

The lockdown at the nearby elementary school was lifted once the devices were deemed stable and removed. Parents received text alerts advising them that students were safe and that dismissal would proceed on schedule.
