South High School Bomb Threat Update: Torrance Police Search Campus After Lockdown

TORRANCE, California — South High School in Torrance was placed on lockdown Wednesday, September 23, 2026, after police received a telephone call claiming that multiple bombs had been placed on the campus, prompting a large law-enforcement response, nearby evacuations and an extensive search.

The Torrance Police Department said its Communications Center received the call shortly after 11:30 a.m. The caller reported multiple bombs at South High School before hanging up on dispatchers. Officers immediately responded, and school administrators placed the campus on lockdown.

Initial searches found nothing suspicious, while explosive-detection K-9 teams brought in through mutual aid conducted a systematic sweep of the school. Police ultimately cleared the scene at approximately 4:30 p.m., according to subsequent local reporting.

No explosion or injuries were reported.

What Happened at South High School in Torrance?

The incident began shortly after 11:30 a.m. Wednesday when Torrance police received a call alleging that multiple explosive devices were somewhere on the South High School campus.

The caller then disconnected.

Police responded to the school at 4801 Pacific Coast Highway, near Calle Mayor, and administrators initiated a lockdown while officers began searching the property.

Because authorities could not immediately determine whether the threat was credible, officers treated the report seriously and established a significant police presence around the campus.

Police Found Nothing Suspicious During Initial Search

Torrance Police said preliminary assessments by responding officers and personnel from the department’s Real Time Response Center did not uncover anything suspicious.

Because the reported threat involved multiple bombs, authorities continued searching rather than immediately ending the lockdown.

Explosive-detection K-9 teams from other agencies were requested through mutual aid and conducted a systematic sweep of the campus.

By the time the scene was cleared later Wednesday afternoon, no explosive device had been publicly reported as discovered.

Nearby Homes Evacuated as a Precaution

The response extended beyond school grounds.

Police escorted pedestrians away from the immediate area and evacuated several nearby homes as a precaution while officers investigated the bomb threat.

Authorities also issued a Torrance Alert concerning police activity around Pacific Coast Highway and Calle Mayor and asked members of the public to avoid the area.

The measures reflected the uncertainty surrounding the caller’s claim rather than confirmation that explosives were actually present.

Richardson Middle School Takes Precautionary Measures

Nearby Richardson Middle School also implemented precautionary measures because of its proximity to South High School, according to Torrance Police.

Additional local reporting, citing Torrance Unified School District communications, said Richardson and Calle Mayor middle schools sheltered in place during portions of the investigation.

There was no publicly confirmed separate bomb threat against those campuses.

Parents Directed to Ross Parking Lot

As the investigation continued, police asked parents arriving to collect students to wait at the Ross parking lot on Pacific Coast Highway.

Authorities initially said students would not be released until officers had completed a full search and determined that the campus was safe.

The controlled release was intended to prevent parents and vehicles from entering an active law-enforcement perimeter and interfering with the search.

When Was the South High School Lockdown Lifted?

The police response continued for several hours Wednesday afternoon.

Later reporting said authorities cleared the scene at around 4:30 p.m. after completing their search.

There was no confirmed explosion, and no injuries associated with the bomb threat were reported.

This means headlines describing the incident as an active lockdown “today” should now be updated to reflect that the emergency occurred on September 23 and has since been resolved.

Was a Bomb Found at South High School?

No bomb or suspicious device was publicly reported as found.

Torrance Police specifically said that preliminary searches did not uncover anything suspicious before explosive-detection K-9 teams continued the campus sweep.

Authorities later cleared the scene.

That does not make the original threat insignificant. Bomb threats can result in criminal investigations even when no explosive device is ultimately located.

Who Made the Bomb Threat?

Police have not publicly identified the caller.

The official statement says only that someone called the Torrance Police Department Communications Center, claimed there were multiple bombs on the campus and then hung up.

No publicly available information reviewed identifies:

  • the caller’s name,
  • age,
  • location,
  • motive,
  • or whether an arrest has been made.

The investigation therefore remains relevant even after the campus search concluded.

No Active Shooter Reported

The South High School emergency involved a bomb threat, not a confirmed school shooting or active-shooter incident.

No gunfire was reported in the official Torrance Police statement, and no shooting injuries were associated with the lockdown.

This distinction is important because social-media posts during rapidly developing school emergencies can sometimes incorrectly describe a large police response as an active-shooter situation.

Significant Police Presence Around Pacific Coast Highway

Residents and motorists saw a substantial law-enforcement presence around South High School during the response.

Police advised the public to avoid the area around Pacific Coast Highway and Calle Mayor while officers worked.

The deployment included regular officers, specialized personnel and explosive-detection K-9 teams obtained through mutual aid.

Traffic and access around the school were affected while the investigation remained active.

Bomb Threat Remains Under Investigation

Even though no explosive device was reported found, police may continue investigating the origin of the threatening call.

Investigators can potentially examine:

  • telephone records,
  • dispatch recordings,
  • available digital evidence,
  • surveillance footage,
  • witness information,
  • and other evidence connected with the communication.

Torrance Police identified the case as DR #260038385.

No arrest or suspect identity had been publicly announced in the latest information reviewed.
