South High School Bomb Threat in Torrance: Lockdown, Police Search and Latest Update

TORRANCE, California — South High School in Torrance was placed on lockdown Wednesday, September 23, 2026, after an unidentified caller reported that multiple bombs were on the school campus, prompting a major police response, precautionary evacuations and an extensive search involving explosive-detection K-9 teams.

The Torrance Police Department said its Communications Center received the call shortly after 11:30 a.m. The caller reported multiple bombs and then hung up on dispatchers. Officers immediately responded to South High School at 4801 Pacific Coast Highway.

School administrators placed the campus on lockdown while officers secured the area.

Police said their initial assessment found nothing suspicious, but authorities continued searching the campus as a precaution. Explosive-detection K-9 teams were brought in through mutual aid to conduct a systematic sweep.

Local reporting later indicated that police cleared the scene at approximately 4:30 p.m.

What Happened at South High School in Torrance?

The emergency began shortly after 11:30 a.m. Wednesday when Torrance police received a telephone call claiming that multiple explosive devices had been placed at South High School.

According to the official Torrance Police Department statement, the caller disconnected before dispatchers could obtain additional information.

Officers quickly responded and established a substantial police presence around the campus.

Because authorities could not immediately determine whether the threat was genuine, school officials placed students and staff under lockdown while police began investigating.

The response continued for several hours while officers and specialized K-9 teams searched the campus.

South High School Bomb Threat Incident Data

Were Multiple Bombs Actually Found at South High School?

There is no confirmation that any explosive device was found.

The phrase “multiple bombs” describes what the caller told police, not what officers discovered on campus.

Torrance police specifically said preliminary assessments by officers and the department’s Real Time Response Center had found nothing suspicious.

Police nevertheless treated the threat seriously and continued searching the entire campus before allowing normal activity to resume.

This distinction is important: a bomb threat was confirmed, but the existence of actual bombs was not.

Bomb-Sniffing K-9 Teams Search the Campus

Mutual-aid police K-9 teams trained to detect explosives were requested to assist.

The dogs and their handlers conducted a systematic sweep of the school while students remained on campus.

The extended search helps explain why students were not immediately released even after police reported that the preliminary investigation had revealed nothing suspicious.

Authorities said students would only be released once the campus had been thoroughly searched and considered safe.

Nearby Homes Evacuated as a Precaution

The response was not limited to South High School.

Police escorted pedestrians away from the immediate area and evacuated several nearby residences as a safety precaution.

Officials also issued a Torrance Alert concerning police activity near Pacific Coast Highway and Calle Mayor, asking members of the public to avoid the area.

The measures were precautionary and did not indicate that police had located an explosive device.

Richardson Middle School Takes Precautionary Measures

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

The official police release did not state that a separate bomb threat had been directed at Richardson. Rather, authorities took precautions because of the developing emergency at South High.

Reports also indicated that nearby schools adjusted operations while police investigated.

Parents Directed to Ross Parking Lot

During the lockdown, parents began arriving near South High School seeking information about their children.

Police instructed parents to park at the Ross parking lot on Pacific Coast Highway and wait there rather than approaching the school.

Authorities emphasized that students would not be released until officers had completed the campus search and determined the area was safe.

Police and school officials worked together on a reunification plan while the investigation continued.

When Was the South High School Lockdown Lifted?

Local reporting indicates that police cleared the scene at about 4:30 p.m. Wednesday after completing their search.

Earlier in the afternoon, the Torrance Police Department had described the investigation as active and warned that the process would take time because officers needed to safely search the school.

No explosion was reported, and no confirmed explosive device was identified in the information released after the response.

Were Any Students or Staff Injured?

No injuries connected to an explosion or explosive device were reported.

There was also no indication in the official information reviewed that anyone had been harmed during the police response.

The major disruption involved the lockdown, campus search, nearby evacuations and restrictions around the school.

Who Made the Bomb Threat?

The identity of the caller had not been publicly released as of the latest update.

Police said only that someone contacted the Torrance Police Department Communications Center, reported multiple bombs at South High and then hung up.

The investigation therefore extends beyond determining whether explosives were present.

Authorities may also examine telephone information and other evidence in an effort to identify who made the call.

The Torrance Police Department lists the case under DR #260038385.

False Bomb Threats Can Trigger Major Emergency Responses

Even when no device is ultimately located, reports of explosives at a school require authorities to respond as though the threat could be genuine until evidence establishes otherwise.

Such incidents can result in:

• lockdowns,

• evacuations,

• searches by explosive-detection dogs,

• road restrictions,

• large police deployments,

• disruption to nearby schools and homes, and

• criminal investigations into the person responsible.

The extensive South High response reflected that precautionary approach.

South High School Location

South High School is part of the Torrance Unified School District and is located at 4801 Pacific Coast Highway in Torrance.

The school sits near Calle Mayor and Richardson Middle School, explaining why police activity affected a wider area around the campus.
