Confirmed HoaxDetermined to be a hoax. The institutional response is documented because it reveals how the alert system performed under a perceived real threat.

On February 20, 2025 at approximately 4:30 PM EST, Clark Atlanta University received a bomb threat that triggered a campus lockdown and cascading shelter-in-place orders across the Atlanta University Center consortium. Spelman College, Morehouse College, and Morris Brown all issued precautionary orders due to physical proximity. The all-clear was issued the same evening after a thorough Atlanta Police Department sweep. The threat came nine months before the September 11, 2025 multi-HBCU lockdown wave and was an early signal of the renewed HBCU threat campaign of 2025.

SPELMAN ALERT: A bomb threat has been reported on the CAU campus. Students on CAU's campus are asked to shelter in place. All others are asked to stay clear of the CAU campus until further notice.
The 4:30 PM EST timestamp is taken directly from the Spelman College alerts archive headline
This Spelman alert is unusual in that it does not refer to a threat against Spelman itself — instead, it provides a proximity-based shelter-in-place notification triggered by an Atlanta University Center neighbor
The phrase 'students on CAU's campus' acknowledges that some Spelman students may be physically present at CAU due to the AUC's open cross-registration and shared facilities, a geography unique to the Atlanta HBCU consortium

Spelman ALERT: The shelter-in-place has been lifted. Everyone is reminded to stay vigilant at all times. If you observe anything suspicious, please report it to public safety right away. Remember if you See Something, Say Something.
Verbatim text confirmed from Spelman College's official alert archive page titled 'SPELMAN ALERT: CAU Campus - ALL CLEAR (2-20-2025)', last updated February 21, 2025 at 6:57 AM EST — the same source and text confirmed in the parallel Spelman College case file
Spelman issued the all-clear for a CAU incident — a notable example of an HBCU institution issuing emergency notifications for a sister institution rather than only its own
The all-clear came roughly 14 hours after the initial shelter alert, indicating the bomb-robot sweep, K-9 sweep, or police investigation extended well into the night
Context

Background

Clark Atlanta University is one of four institutions in the Atlanta University Center consortium, alongside Spelman College, Morehouse College, and Morris Brown College — a geographic cluster unique in American higher education for its density of historically Black institutions sharing facilities, cross-registered students, and contiguous campus geography. On the afternoon of February 20, 2025 at approximately 4:30 PM EST, CAU received a bomb threat that prompted Atlanta Police and CAU Public Safety to lock down the campus and conduct a sweep. Because of AUC's geographic intimacy, Spelman, Morehouse, and Morris Brown each issued cascading shelter-in-place orders for their own students — even though those institutions did not themselves receive direct threats. The Spelman alert text, preserved verbatim in the Spelman archive, is unusually direct in stating 'students on CAU's campus are asked to shelter in place' — language that acknowledges shared physical space across institutional boundaries. The all-clear was issued the same evening after no devices were found. The February 20 threat predated the September 11, 2025 multi-HBCU lockdown wave by nearly seven months and is an early datapoint in the renewed 2025 HBCU threat campaign. The CAU incident also sits in a longer institutional pattern at Clark Atlanta, which has appeared in this archive for bomb threats and homecoming shootings in prior years.
Analysis

Key Findings

The 4:30 PM EST CAU bomb threat triggered cascading shelter-in-place orders at three other AUC institutions — a unique cross-campus alert pattern enabled by the AUC's geographic intimacy
Spelman's verbatim alert language ('students on CAU's campus are asked to shelter in place') is one of few examples in this archive of an HBCU institution issuing emergency notifications for a sister institution
The February 2025 threat predated the September 11, 2025 multi-HBCU lockdown wave by nearly seven months — making it an early signal of renewed 2025 HBCU targeting
CAU's institutional history shows a consistent pattern of bomb threats and homecoming-period violence requiring repeated emergency-notification activations across multiple years
Outcome
No explosive devices were found on the CAU campus. The shelter-in-place orders at CAU, Spelman, Morehouse, and Morris Brown were lifted by evening. Atlanta Police and CAU Public Safety completed a thorough campus sweep before lifting the lockdown.
