Alcorn State University has resumed operations after being locked down for several hours Thursday morning. 

An update posted to Facebook around noon notes that Alcorn was among several historically Black colleges and universities that received emailed threats. The post does not provide details about the nature of the threats.

“There is no ongoing threat, and the campus is secure,” the statement read.

The post notes that some security precautions remain in place, and that access to the campus is restricted.

University officials would not provide additional information Thursday morning.

The Mississippi Institutions of Higher Learning’s Board of Trustees, which had a regularly scheduled meeting Thursday morning, went into closed session to discuss matters including security and personnel plans related to the situation at Alcorn. The board gave no statement about Alcorn when they returned to open session and adjourned the meeting.

In February of 2022, most HBCUs in Mississippi locked down and pivoted to virtual classes after receiving bomb threats. Other HBCUs across the country also reported bomb threats that day, which was the first day of Black History Month. That year, the spate of bomb threats prompted the American Council on Education and other organizations to ask Congress to support and protect HBCUs from such “acts of terror.”

The incidents continued. There was another wave of threats against HBCUs in September.

On Thursday, other HBCUs including Morris Brown College and Morehouse University in Atlanta, Savannah State University in Georgia, Wiley University in Marshall, Texas, also received threats, according to news reports. It is unclear how many schools also received threats Thursday, and whether the incidents are connected.
